Description

[Technical field]

[0001] The present invention relates to a booth and a booth system. [Background technology]

[0002] 2. Description of the Related Art In offices, public facilities and the like, booths are known in which a plurality of panels are connected to form a space for individual office work or work (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Registered Utility Model No. 3009775 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in such booths, there is a high possibility that the sounds of the users working in the booth, as well as the voices of those working on the phone or during online conferences, will leak out of the booth. On the other hand, there is a high possibility that noise from outside the booth will leak into the booth.

[0005] Therefore, the object of the present invention is to provide a booth and booth system that can reduce sound leakage from inside the booth to the outside, and sound entering from the outside to the inside, with the minimum necessary sound absorption and sound insulation functions, in accordance with the environment inside and outside the booth. [Means for solving the problem]

[0006] (1) A booth according to one embodiment of the present invention comprises a first panel and a second panel connected to each other, and a work space is formed by the first panel and the second panel. The first panel has a sound absorbing section with sound absorbing function on the inside of the booth facing the work space, and a sound insulating section with sound insulating function on the outside of the booth opposite the inside of the booth. The second panel is connected to one end of the direction in which the first panel extends in a planar view, extends in a direction intersecting the direction in which the first panel extends in the planar view, and has the sound absorbing section on the outside of the booth and the sound insulating section on the inside of the booth. According to this aspect, when a user in the booth faces the first panel, the sound emitted by the user is absorbed by the sound absorbing portion of the first panel, so that sound leakage to the outside of the booth can be suppressed. On the other hand, when the ear of the user in the booth is located on the side of the second panel, the noise outside the booth is absorbed by the sound absorbing portion of the second panel, so that the effect of the noise on the user in the booth can be suppressed. Therefore, with the minimum necessary sound absorbing and sound blocking functions according to the environment inside and outside the booth, sound leakage from inside the booth to the outside and sound entering from outside the booth to inside the booth can be reduced.

[0007] (2) In the above aspect (1), the booth may further include a third panel connected to the other end of the first panel in the direction in which the first panel extends when viewed in the planar view and extending in a direction intersecting the direction in which the first panel extends, and the third panel may have the sound-absorbing portion on the inside of the booth and the sound-proof portion on the outside of the booth. According to this aspect, the sound emitted by the user is absorbed by the sound absorbing portion of the third panel, so that sound leakage from inside the booth to the outside can be suppressed.

[0008] (3) In the above aspect (2), the booth may further include a top panel having an upwardly facing work surface in the work space. According to this aspect, since the work space has a tabletop, the direction in which the user faces is surrounded on three sides by the first panel, the second panel, and the third panel, so sound leakage from inside the booth to the outside and sound coming in from the outside to the inside of the booth can be suitably reduced.

[0009] (4) In the above aspect (3), the top plate may have an inclined edge portion on the edge opposite the first panel in the planar view, the inclined edge portion extending away from the first panel as it moves toward the opposite side to the second panel in the extension direction of the first panel. According to this aspect, a user who uses the work surface of the tabletop facing the inclined edge of the tabletop is prompted to face the corner between the first and third panels, rather than directly facing the second panel. This allows the sound emitted by the user to be absorbed by the sound absorbing parts of the first and third panels, thereby preventing sound from leaking outside the booth.

[0010] (5) A booth system according to one embodiment of the present invention comprises a basic booth which is a booth according to any one of the above embodiments (1) to (4) and an extension booth which is arranged next to the basic booth across the second panel, wherein the extension booth comprises a front panel which is arranged on one side of the front in a direction which intersects with the direction in which the first panel extends in the plan view, and a side panel which is arranged on the side opposite the basic booth in the plan view. According to this aspect, even if a user in the extension booth faces the basic booth while talking, etc., the sound absorbing section is provided on the outside of the basic booth, so sound leakage from the extension booth to the basic booth can be reduced.

[0011] (6) In the above aspect (5), the front panel may have the sound-absorbing section on the inside of the booth facing the second work space formed by the extension booth, and the sound-proofing section on the outside of the booth opposite the inside of the booth facing the second work space, and the side panel may have the sound-absorbing section on the outside of the booth opposite the inside of the booth facing the second work space, and the sound-proofing section on the inside of the booth facing the second work space. According to this embodiment, when a user in the extension booth faces the front panel, the sound emitted by the user is absorbed by the sound absorbing portion of the front panel, so that sound leakage to the outside of the extension booth can be suppressed. On the other hand, when the ear of the user in the extension booth is located on the side panel side, the noise outside the extension booth is absorbed by the sound absorbing portion of the side panel, so that the effect of noise on the user in the extension booth can be suppressed. Therefore, with the minimum necessary sound absorption and sound insulation function according to the environment inside and outside the extension booth, sound leakage from inside the extension booth to the outside and sound entering from outside the extension booth to inside the extension booth can be reduced.

[0012] (7) In the above aspect (6), the expansion booth may be provided with a top plate having a work surface facing upward, and the top plate may be provided with an inclined edge portion on the edge opposite the front panel in the plan view, the edge portion extending at an angle away from the front panel as it moves toward the opposite side of the side panel in the direction in which the front panel extends. According to this aspect, a user who uses the work surface of the tabletop facing the inclined edge of the tabletop in the extension booth is prompted to face the corner between the front panel and the second panel, rather than facing the side panel directly. As a result, the sound emitted by the user in the extension booth is absorbed by the sound absorbing parts of the front panel and the second panel, so sound leakage from the extension booth to the basic booth can be suppressed. Effect of the Invention

[0013] According to one aspect of the present invention, sound leakage from inside the booth to the outside and sound intrusion from outside the booth to the inside can be reduced with the minimum necessary sound absorption and sound insulation functions, in accordance with the environment inside and outside the booth.

[0015] First Embodiment A first embodiment of the present invention will be described below with reference to Figs. 1 to 14. In the first embodiment, a booth system in which multiple booths are connected will be described. In the following description, expressions indicating relative or absolute arrangement, such as "parallel", "orthogonal", "center", and "coaxial", do not only mean such an arrangement strictly, but also include a state in which there is a relative displacement with a tolerance or an angle or distance to the extent that the same function is obtained. In the drawings used in the following description, the scale of each component may be changed to make each component recognizable.

[0016] <Booth System> FIG. 1 is a top view of a booth system 1 according to the first embodiment. As shown in Fig. 1, the booth system 1 includes a basic booth 2 and an extension booth 3. The booth system 1 is placed on a floor surface F. For example, the booth system 1 is used with the basic booth 2 and the extension booth 3 connected together. For example, the booth system 1 is installed in work spaces or meeting spaces in offices, public facilities, schools, etc. The installation location of the booth system 1 is not limited to the above and can be changed as appropriate.

[0017] In the following description, an XYZ coordinate system is shown as a three-dimensional orthogonal coordinate system in each figure as appropriate. In the XYZ coordinate system, the Z-axis direction is the vertical direction. The vertical direction is the direction perpendicular to the floor surface F on which the booth system 1 is placed (corresponding to the up-down direction). The +Z side is the upper side, and may be simply referred to as the "upper side" below. The -Z side is the lower side, and may be simply referred to as the "lower side" below. The X-axis direction is a direction perpendicular to the Z-axis direction (corresponding to a first direction intersecting the up-down direction), and is the left-right direction of the booth system 1, and may be simply referred to as the "width direction" below. The +X side is the right side of the booth system 1, and may be simply referred to as the "right side" below. The -X side is the left side of the booth system 1, and may be simply referred to as the "left side" below. The -X side corresponds to one side of the first direction, and the +X side corresponds to the other side of the first direction. The Y-axis direction is a direction perpendicular to the X-axis direction and the Z-axis direction, and is the front-rear direction of the booth system 1. The +Y side is the rear side of the booth system 1, and may hereinafter be simply referred to as the "rear side." The -Y side is the front side of the booth system 1, and may hereinafter be simply referred to as the "front side." Note that the terms "upper," "lower," "front," "rear," "left side," and "right side" are simply names used to explain the relative positional relationships of the various parts, and the actual positional relationships, etc. may be other than those indicated by these names.

[0018] <Basic booth> FIG. 2 is a perspective view of the basic booth 2 of the first embodiment. 1 and 2, a first work space 10 is formed in the basic booth 2. The basic booth 2 includes a basic booth body 11 (an example of a first booth, hereinafter also referred to as "the first booth 11"), a basic booth side top plate 12 (an example of a functional member), and a basic booth side inclined panel 13. The basic booth body 11 has a shape along three sides of a rectangle in a plan view (a U-shape in a plan view). The basic booth body 11 includes a first panel 15, a second panel 16, and a third panel 17.

[0019] The first panel 15 is a rectangular plate that is long in the vertical direction. The left-right direction when viewed horizontally from a direction perpendicular to the inner surface of the first panel 15 (the surface facing inward of the basic booth body 11) corresponds to the width direction of the first panel 15. The direction perpendicular to the inner surface of the first panel 15 in the horizontal plane is the thickness direction of the first panel 15, which corresponds to the front-rear direction. In the front-rear direction, the first panel 15 side of the basic booth 2 corresponds to the rear side, and the opposite side corresponds to the front side.

[0020] The second panel 16 and the third panel 17 are connected to both ends of the first panel 15 in the direction in which it extends in a plan view. The second panel 16 is a rectangular plate that is long in the up-down direction. The second panel 16 is connected to the left end of the first panel 15 (an example of one end of the direction in which the first panel 15 extends in a plan view). The second panel 16 extends in a direction perpendicular to the direction in which the first panel 15 extends. The second panel 16 extends forward from the left end of the first panel 15.

[0021] The third panel 17 is a rectangular plate that is long in the up-down direction. The third panel 17 is connected to the right end of the first panel 15 (an example of the other end in the direction in which the first panel 15 extends in a plan view). The third panel 17 extends in a direction perpendicular to the direction in which the first panel 15 extends. The third panel 17 extends forward from the right end of the first panel 15. The second panel 16 and the third panel 17 extend parallel to each other and perpendicular to the inner surface of the first panel 15 in a plan view. The second panel 16 and the third panel 17 extend in the front-rear direction while facing each other in the width direction.

[0022] In this embodiment, the first panel 15 and the third panel 17 are each composed of panels having a similar structure (specifically, a pair of a first plate-shaped portion 31 and a second plate-shaped portion 32). On the other hand, the second panel 16 is composed of a panel having a structure different from that of the first panel 15 and the third panel 17 (specifically, a pair of a third plate-shaped portion 75 and a fourth plate-shaped portion 76).

[0023] Inside the basic booth body 11, a basic booth inner space 10 (an example of a work space formed by the basic booth, hereinafter also referred to as "first work space 10") having an opening facing forward is formed by being surrounded by a first panel 15, a second panel 16, and a third panel 17. In the example shown in the figure, the panel width dimension of the first panel 15 on the side facing the basic booth inner space 10 is approximately the same as the panel width dimension of the second panel 16 and the third panel 17 on the side facing the basic booth inner space 10. In the example shown in the figure, the panel width dimension of the second panel 16 on the side facing the basic booth inner space 10 is approximately the same as the panel width dimension of the third panel 17 on the side facing the basic booth inner space 10. Note that the panel width dimensions of the first panel 15, the second panel 16, and the third panel 17 may be the same or different from each other. For example, the panel width dimensions of the first panel 15, the second panel 16, and the third panel 17 can be changed according to the design specifications.

[0024] The basic booth side top plate 12 is disposed within the basic booth body 11. The basic booth side top plate 12 is formed in a flat plate shape having a thickness in the vertical direction. The basic booth side top plate 12 has a work surface 12a facing upward. The upper surface of the basic booth side top plate 12 is used as the work surface 12a. The upper surface of the basic booth side top plate 12 is disposed so as to be aligned along a horizontal plane.

[0025] The basic booth side top plate 12 includes panel side edge portions 12b, 12c, and 12d and front edge portions 12e1 and 12e2. The panel side edge portions 12b, 12c, and 12d include a rear edge portion 12b extending in the width direction along the inner surface of the first panel 15, a right edge portion 12c extending in the front-rear direction along the inner surface of the third panel 17, and a left edge portion 12d extending in the front-rear direction along the inner surface of the second panel 16. The basic booth side top plate 12 is fixed by brackets, screws, etc., with the panel side edge portions 12b, 12c, and 12d aligned with the first panel 15, the second panel 16, and the third panel 17. In the illustrated example, the right edge portion 12c of the panel side edge portions 12b, 12c, and 12d is in contact with the inner surface of the opposing panel (see FIG. 9). The panel side edge portions 12b, 12c, and 12d may be in contact with the inner surface of the opposing panel. The panel side edge portions 12b, 12c, and 12d only need to be close to the inner surface of the opposing panel, and do not have to be in contact with the inner surface of the opposing panel.

[0026] The front edge portions 12e1, 12e2 of the basic booth side top plate 12 include a right front edge portion 12e1 disposed on the third panel 17 side and a left front edge portion 12e2 disposed on the second panel 16 side. The right front edge portion 12e1 extends at an incline rearward so as to gradually approach the first panel 15 from the right end toward the left end. In the example shown in the figure, the right front edge portion 12e1 (excluding the rounded corners) extends linearly from the right end to the left end in a plan view.

[0027] The right end of the right front edge portion 12e1 (excluding the rounded corners) constitutes the right end of the entire front edges 12e1, 12e2. The right end of the right front edge portion 12e1 is connected to the front end of the right edge portion 12c via the rounded corners. The right end of the right front edge portion 12e1 is located rearward of the front end portion of the third panel 17. The left end of the right front edge portion 12e1 is spaced apart from the second panel 16 in the width direction.

[0028] The left front edge 12e2 extends leftward from the left end of the right front edge 12e1 via a curved portion. In the example shown in the figure, the left front edge 12e2 (excluding the rounded corners) extends linearly along the width direction in a plan view and is perpendicular to the inner surface of the second panel 16. The left front edge 12e2 (excluding the rounded corners) constitutes the rearmost portion of the front end edges 12e1, 12e2 and is closest to the first panel 15. In the front end edges 12e1, 12e2, the dimension in the direction in which the right front edge 12e1 extends (the direction connecting the right end and the left end) is longer than the dimension in the direction in which the left front edge 12e2 extends (the width direction).

[0029] Although not shown, the basic booth side top plate 12 may be provided with a wiring insertion portion through which various wiring connected to electrical devices used on the work surface 12a is inserted. For example, a lighting device may be provided above the work surface 12a of the basic booth side top plate 12. Note that the basic booth 2 can be provided with various optional components other than the wiring insertion portion and the lighting device.

[0030] For example, in the basic booth internal space 10, a chair may be provided at a position facing the right front edge portion 12e1. For example, the chair may be configured to be rotatable about an axis along the vertical direction. For example, the chair may be installed on a floor surface F, or may be capable of moving on the floor surface F by casters or the like. For example, the chair may be supported by an arm or the like extending from the basic booth body 11. For example, the manner in which the chair is installed may be changed as appropriate.

[0031] The basic booth side inclined panel 13 is connected to the front end of the second panel 16 (the end of the second panel 16 opposite the first panel 15) in a plan view. The basic booth side inclined panel 13 extends away from the first panel 15 as it moves toward the third panel 17 in the direction in which the first panel 15 extends in a plan view. The basic booth side inclined panel 13 extends at an angle forward as it moves toward the right side from the front end of the second panel 16 in a plan view.

[0032] The tip end of the basic booth side inclined panel 13 (the end of the basic booth side inclined panel 13 opposite to the front end of the second panel 16) is disposed with a gap between it and the front end of the third panel 17. An entrance / exit 19 for entering and exiting the basic booth internal space 10 is formed between the tip end of the basic booth side inclined panel 13 and the front end of the third panel 17.

[0033] In the illustrated example, the basic booth side inclined panel 13 extends linearly in a plan view. The basic booth side inclined panel 13 extends parallel to the right front edge 12e1 of the basic booth side top plate 12 in a plan view. The dimension in the extension direction of the basic booth side inclined panel 13 is shorter than the dimension in the extension direction of the right front edge 12e1 of the basic booth side top plate 12. The basic booth side inclined panel 13 is not limited to extending linearly in a plan view, and may extend in a curved or stepped manner. For example, the manner in which the basic booth side inclined panel 13 extends can be changed according to the design specifications.

[0034] For example, a user of the basic booth 2 enters and exits the basic booth main body 11 (basic booth inner space 10) through an entrance 19 formed between the tip of the basic booth side inclined panel 13 and the front end of the third panel 17. For example, a user of the basic booth 2 sits on a chair in the basic booth 2 and uses the work surface 12a of the basic booth side top plate 12 while facing the right front edge portion 12e1 of the basic booth side top plate 12. At this time, the user of the basic booth 2 does not face the first panel 15 but faces the right front edge portion 12e1 of the basic booth side top plate 12. Then, the user of the basic booth 2 is prompted to face the right end portion of the first panel 15 (the corner portion between the first panel 15 and the third panel 17) in a plan view.

[0035] When a user of the basic booth 2 is encouraged to face the right end of the first panel 15 in a plan view, the basic booth side inclined panel 13 is disposed behind the user. Therefore, the basic booth side inclined panel 13 blocks the view from behind the user. In addition, since an entrance / exit 19 is formed on the right side of the user, the user is prevented from feeling a sense of claustrophobia. In addition, the user can see people approaching from the right side through the entrance / exit 19. In addition, the user inside the basic booth 2 can be seen through the entrance / exit 19 when viewed from outside the basic booth 2.

[0036] <Extension booth> A second work space 20 is formed in the extension booth 3. The extension booth 3 includes an extension booth main body 21 (an example of a second booth, hereinafter also referred to as the "second booth 21"), an extension booth side top plate 22 (an example of a functional member, hereinafter also referred to as the "functional member 22"), and an extension booth side inclined panel 23.

[0037] The extension booth body 21 is L-shaped in a plan view. The extension booth body 21 forms a second work space 20 that is open to the right side (an example of the other side of the first direction intersecting the vertical direction). The extension booth body 21 is disposed adjacent to the basic booth 2 on the left side (an example of one side of the first direction intersecting the vertical direction). The extension booth body 21 includes a front panel 25 and a side panel 26.

[0038] The front panel 25 is disposed on the rear surface of the expansion booth main body 21 (corresponding to the front surface in the second direction intersecting with the first direction in a plan view). The front panel 25 is a rectangular plate that is long in the up-down direction. The front panel 25 extends so as to be connected to the first panel 15 in a plan view. The left-right direction when viewed horizontally from a direction perpendicular to the inner surface of the front panel 25 (the surface facing inward of the expansion booth main body 21) corresponds to the width direction of the front panel 25. The direction perpendicular to the inner surface of the front panel 25 in the horizontal plane is the thickness direction of the front panel 25, which corresponds to the front-rear direction. In the front-rear direction, the front panel 25 side of the expansion booth 3 corresponds to the rear side, and the opposite side corresponds to the front side.

[0039] The side panel 26 is disposed on the left side of the extension booth body 21 (corresponding to the side opposite to the basic booth 2 in plan view). The side panel 26 is connected to the end of the front panel 25 in the direction in which it extends in plan view (the end of the front panel 25 opposite to the first panel 15). The side panel 26 is a rectangular plate that is long in the vertical direction. The side panel 26 is connected to the left end of the front panel 25. The side panel 26 extends in a direction perpendicular to the direction in which the front panel 25 extends. The side panel 26 extends forward from the left end of the front panel 25. The second panel 16 and the side panel 26 are perpendicular to the inner surface of the front panel 25 in plan view and extend parallel to each other. The second panel 16 and the side panel 26 extend in the front-rear direction while facing each other in the width direction.

[0040] In this embodiment, the front panel 25 is composed of a panel having a structure similar to that of the first panel 15 and the third panel 17 (specifically, a pair of a first plate-shaped portion 31 and a second plate-shaped portion 32). On the other hand, the side panel 26 is composed of a panel having a structure different from that of the front panel 25 (specifically, a pair of a third plate-shaped portion 75 and a fourth plate-shaped portion 76). In this embodiment, the side panel 26 is composed of a panel having a structure similar to that of the second panel 16.

[0041] Inside the extension booth main body 21, an extension booth internal space 20 (an example of a second work space, hereinafter also referred to as "work space 20") is formed by a front panel 25 and a side panel 26. When the basic booth 2 and the extension booth main body 21 are connected to each other, the extension booth internal space 20 has an opening facing forward, surrounded by the second panel 16 constituting the basic booth main body 11 and the front panel 25 and side panel 26 constituting the extension booth main body 21. The basic booth internal space 10 and the extension booth internal space 20, which are work spaces, are partitioned by the second panel 16.

[0042] In the illustrated example, the panel width dimension of the side of the front panel 25 facing the extension booth space 20 is approximately the same as the panel width dimension of the side of the side panel 26 facing the extension booth space 20. In the illustrated example, the panel width dimension of the side of the side panel 26 facing the extension booth space 20 is approximately the same as the panel width dimension of the side of the second panel 16 facing the extension booth space 20. The panel width dimensions of the front panel 25 and the side panel 26 may be the same or different. For example, the panel width dimensions of the front panel 25 and the side panel 26 can be changed according to the design specifications.

[0043] The extension booth side top plate 22 is disposed within the extension booth main body 21. The extension booth side top plate 22 is formed in a flat plate shape having a thickness in the vertical direction. The extension booth side top plate 22 has a work surface 22a facing upward. The upper surface of the extension booth side top plate 22 is used as the work surface 22a. The upper surface of the extension booth side top plate 22 is disposed so as to be aligned along a horizontal plane.

[0044] The extension booth side top plate 22 includes panel side edge portions 22b, 22c, 22d and front edge portions 22e1, 22e2. The panel side edge portions 22b, 22c, 22d include a rear edge portion 22b extending in the width direction along the inner surface of the front panel 25, a right edge portion 22c extending in the front-rear direction along the inner surface of the second panel 16 (the outer surface of the second panel 16 when viewed from the basic booth 2), and a left edge portion 22d extending in the front-rear direction along the inner surface of the side panel 26. The extension booth side top plate 22 is fixed by brackets, screws, etc. with the panel side edge portions 22b, 22c, 22d aligned with the front panel 25, the second panel 16, and the side panel 26. In the illustrated example, the right edge portion 22c of the panel side edge portions 22b, 22c, 22d is in contact with the inner surface of the opposing panel (see FIG. 9). The panel side edge portions 22b, 22c, and 22d may be in contact with the inner surface of the opposing panel. The panel side edge portions 22b, 22c, and 22d may be in close proximity to the inner surface of the opposing panel, and may not be in contact with the inner surface of the opposing panel.

[0045] The front edge portions 22e1, 22e2 of the extension booth side top plate 22 include a right front edge portion 22e1 disposed on the second panel 16 side and a left front edge portion 22e2 disposed on the side panel 26 side. The right front edge portion 22e1 extends at an incline backward so as to gradually approach the front panel 25 from the right end toward the left end. In the example shown in the figure, the right front edge portion 22e1 (excluding the rounded corners) extends linearly from the right end to the left end in a plan view.

[0046] The right end of the right front edge portion 22e1 (excluding the rounded corners) constitutes the right end of the entire front edges 22e1, 22e2. The right end of the right front edge portion 22e1 is connected to the front end of the right edge portion 22c via the rounded corners. The right end of the right front edge portion 22e1 is located rearward of the front end portion of the second panel 16. The left end of the right front edge portion 22e1 is spaced apart from the side panel 26 in the width direction.

[0047] The left front edge 22e2 extends leftward from the left end of the right front edge 22e1 via a curved portion. In the example shown in the figure, the left front edge 22e2 (excluding the rounded corners) extends linearly along the width direction in a plan view and is perpendicular to the inner surface of the side panel 26. The left front edge 22e2 (excluding the rounded corners) constitutes the rearmost portion of the front end edges 22e1, 22e2 and is closest to the front panel 25. In the front end edges 22e1, 22e2, the dimension in the direction in which the right front edge 22e1 extends (the direction connecting the right end and the left end) is longer than the dimension in the direction in which the left front edge 22e2 extends (the width direction).

[0048] Although not shown, the extension booth side top plate 22 may be provided with a wiring insertion portion through which various wiring connected to electrical devices used on the work surface 22a is inserted. For example, a lighting device may be provided above the work surface 22a of the extension booth side top plate 22. Note that the extension booth 3 can be provided with various optional components other than the wiring insertion portion and the lighting device.

[0049] For example, in the extension booth inner space 20, a chair may be provided at a position facing the right front edge portion 22e1. For example, the chair may be configured to be rotatable about an axis along the vertical direction. For example, the chair may be installed on the floor surface F, or may be able to run on the floor surface F by casters or the like. For example, the chair may be supported by an arm or the like extending from the extension booth main body 21. For example, the installation manner of the chair can be changed as appropriate.

[0050] The extension booth side inclined panel 23 is connected to the front end of the side panel 26 in a plan view (the end of the side panel 26 opposite the front panel 25). The extension booth side inclined panel 23 extends so as to move away from the front panel 25 as it moves toward the second panel 16 in the direction in which the front panel 25 extends in a plan view. The extension booth side inclined panel 23 extends at an angle forward as it moves from the front end of the side panel 26 toward the right side in a plan view.

[0051] The tip end of the extension booth side inclined panel 23 (the end of the extension booth side inclined panel 23 opposite to the front end of the side panel 26) is disposed with a gap between it and the front end of the second panel 16. Between the tip end of the extension booth side inclined panel 23 and the front end of the second panel 16, an entrance / exit 29 for entering and exiting the extension booth internal space 20 is formed.

[0052] In the illustrated example, the extension booth side inclined panel 23 extends linearly in plan view. The extension booth side inclined panel 23 extends parallel to the right front edge 22e1 of the extension booth side top plate 22 in plan view. The dimension in the direction in which the extension booth side inclined panel 23 extends is shorter than the dimension in the direction in which the right front edge 22e1 of the extension booth side top plate 22 extends. The extension booth side inclined panel 23 is not limited to a linear shape in plan view, and may extend in a curved or stepped shape. For example, the manner in which the extension booth side inclined panel 23 extends can be changed according to design specifications.

[0053] For example, a user of the extension booth 3 enters and exits the inside of the extension booth main body 21 (the space inside the extension booth 20) through an entrance 29 formed between the tip of the extension booth side inclined panel 23 and the front end of the second panel 16. For example, a user of the extension booth 3 sits on a chair in the extension booth 3 and uses the work surface 22a of the extension booth side top plate 22 while facing the right front edge portion 22e1 of the extension booth side top plate 22. At this time, the user of the extension booth 3 does not face the front panel 25 directly, but faces the right front edge portion 22e1 of the extension booth side top plate 22. Then, the user of the extension booth 3 is prompted to face the right end portion of the front panel 25 (the corner portion between the front panel 25 and the second panel 16) in a plan view.

[0054] When a user of the extension booth 3 is encouraged to face the right end of the front panel 25 in a plan view, the extension booth side inclined panel 23 is disposed behind the user. Therefore, the extension booth side inclined panel 23 blocks the view from behind the user. In addition, since an entrance / exit 29 is formed on the right side of the user, the user is prevented from feeling a sense of obstruction. In addition, the user can see people approaching from the right side through the entrance / exit 29. In addition, the user inside the extension booth 3 can be seen through the entrance / exit 29 when viewed from outside the extension booth 3.

[0055] <Panel body configuration> Fig. 3 is an exploded perspective view of the panel body 30 of the first embodiment. Fig. 4 is a perspective view of the first plate-shaped portion 31 of the first embodiment. Fig. 5 is a perspective view of the second plate-shaped portion 32 of the first embodiment. 3 to 5, the panel body 30 includes a pair of plate-like portions 31, 32, and a sound-absorbing material 33 that is disposed between the pair of plate-like portions 31, 32 and has a sound-absorbing surface 33a.

[0056] A through hole 43 is formed in the first plate-shaped portion 31 (one of the pair of plate-shaped portions 31, 32 that is arranged inside the booth). The through hole 43 is formed in a position facing the sound-absorbing material 33. The panel body 30 has a sound-absorbing portion with sound-absorbing function on one side of the inside and outside of the booth. The panel body 30 has a sound-insulating portion with sound-insulating function on the other side of the inside and outside of the booth. Hereinafter, of the pair of plate-shaped portions 31, 32, the one that is arranged inside the booth when viewed from the basic booth 2 is also referred to as the "first plate-shaped portion 31," and the one that is arranged outside the booth when viewed from the basic booth 2 is also referred to as the "second plate-shaped portion 32."

[0057] For example, the first plate-shaped portion 31 is formed of a metal plate such as a steel plate. For example, the first plate-shaped portion 31 may be covered with a skin material or the like. The first plate-shaped portion 31 includes a first main surface portion 40 that forms the entire surface of the panel body 30 that faces the inside of the booth, and a first flange portion 41 that rises from the outer edge of the first main surface portion 40.

[0058] The first main surface portion 40 has a rectangular shape corresponding to the outer shape of the panel body 30. The first main surface portion 40 has a first insertion hole 42 formed at a height position corresponding to the top plate. The first insertion hole 42 is disposed at a position facing the second cross beams 56A, 56B. The first flange portion 41 is formed so as to protrude from the entire outer edge of the first main surface portion 40 toward the second plate-shaped portion 32. The first main surface portion 40 has a through hole 43 formed at a position different from the first insertion hole 42. In the example shown in the figure, the through hole 43 is formed at a position above the first insertion hole 42 in the first main surface portion 40.

[0059] For example, the second plate-shaped portion 32 is formed of a metal plate such as a steel plate. For example, the second plate-shaped portion 32 may be covered with a skin material or the like. The second plate-shaped portion 32 includes a second main surface portion 50 that forms the entire surface of the panel body 30 that faces the outside of the booth, and a second flange portion 51 that rises from the outer edge of the second main surface portion 50.

[0060] The second main surface portion 50 has a rectangular shape corresponding to the outer shape of the panel body 30. The second main surface portion 50 has substantially the same shape as the outer shape of the first main surface portion 40 when viewed in the thickness direction of the panel body 30. The second main surface portion 50 is disposed parallel to the first main surface portion 40. The second flange portion 51 is formed so as to protrude from the entire outer edge of the second main surface portion 50 toward the first plate-shaped portion 31. The second main surface portion 50 does not have a hole (a through hole formed at a position facing the sound-absorbing material 33) equivalent to the through hole 43 of the first main surface portion 40.

[0061] The panel body 30 is disposed between the pair of plate-shaped portions 31, 32 and further includes first vertical rods 45A, 45B and first horizontal beams 46A, 46B joined to the first plate-shaped portion 31. Each of the first vertical rods 45A, 45B and the first horizontal beams 46A, 46B is formed to include a portion having a U-shaped cross section. Each of the first vertical rods 45A, 45B and the first horizontal beams 46A, 46B is joined to the first plate-shaped portion 31 so as to form a closed cross section.

[0062] The first vertical rods 45A, 45B extend in the vertical direction. The first vertical rods 45A, 45B are provided as a pair with a horizontal gap between them. Each of the first vertical rods 45A, 45B extends from the vicinity of the upper corner to the vicinity of the lower corner of the first plate-shaped portion 31 as viewed in the thickness direction of the panel body 30. At least one engagement hole 45h (three in the illustrated example) is formed in each of the first vertical rods 45A, 45B. In the illustrated example, the engagement hole 45h is a hexagonal shape (a shape combining a rectangle and a trapezoid) that is elongated in the vertical direction as viewed in the thickness direction of the panel body 30. The lower edge of the engagement hole 45h extends linearly along the horizontal direction as viewed in the thickness direction of the panel body 30.

[0063] The first cross beams 46A, 46B extend in the horizontal direction. The first cross beams 46A, 46B are provided in pairs with a gap in the vertical direction. The upper first cross beam 46A extends from near one corner of the upper side of the first plate-shaped portion 31 to near the other corner when viewed from the thickness direction of the panel body 30. The lower first cross beam 46B extends from near one corner of the lower side of the first plate-shaped portion 31 to near the other corner when viewed from the thickness direction of the panel body 30. The first cross beams 46A, 46B protrude toward the second plate-shaped portion 32 side more than the first vertical bars 45A, 45B. The first cross beams 46A, 46B are arranged so as to be close to or in contact with the second main surface portion 50 of the second plate-shaped portion 32.

[0064] The panel body 30 is disposed between the pair of plate-shaped portions 31, 32 and further includes second vertical rods 55A, 55B and second horizontal beams 56A, 56B joined to the second plate-shaped portion 32. Each of the second vertical rods 55A, 55B and the second horizontal beams 56A, 56B is formed to include a portion having a U-shaped cross section. Each of the second vertical rods 55A, 55B and the second horizontal beams 56A, 56B is joined to the second plate-shaped portion 32 so as to form a closed cross section.

[0065] The second vertical rods 55A, 55B extend in the vertical direction. The second vertical rods 55A, 55B are provided as a pair with a horizontal gap between them. Each of the second vertical rods 55A, 55B extends from the vicinity of an upper corner of the second plate-shaped portion 32 to the vicinity of a lower corner when viewed from the thickness direction of the panel body 30. The second vertical rods 55A, 55B are arranged so as to entirely overlap the first vertical rods 45A, 45B when viewed from the thickness direction of the panel body 30. The second vertical rods 55A, 55B are arranged so as to be in close proximity to or in contact with the first vertical rods 45A, 45B.

[0066] At least one (three in the illustrated example) engagement claw 57 is formed on each of the second vertical rods 55A and 55B to engage with the engagement hole 45h of each of the first vertical rods 45A and 45B. In the illustrated example, the engagement claw 57 includes a first protruding portion 57a ​​that protrudes from the second vertical rods 55A and 55B toward the first vertical rods 45A and 45B and then extends downward, and a second protruding portion 57b that extends downward from a corner of the first protruding portion 57a ​​(see FIG. 10). For example, the engagement claw 57 is inserted obliquely from above into the engagement hole 45h and engages with the lower edge of the engagement hole 45h from above. At this time, the portion (corner) between the first protruding portion 57a ​​and the second protruding portion 57b of the engagement claw 57 is hooked from above on the lower edge of the engagement hole 45h.

[0067] The second cross beams 56A, 56B extend in the horizontal direction. The second cross beams 56A, 56B are provided in pairs with a gap in the vertical direction. Each of the second cross beams 56A, 56B is disposed between a pair of the first cross beams 46A, 46B when viewed from the thickness direction of the panel body 30. Each of the second cross beams 56A, 56B extends between a pair of the second vertical bars 55A, 55B. The second cross beams 56A, 56B protrude toward the first plate-shaped portion 31 side more than the second vertical bars 55A, 55B. The second cross beams 56A, 56B are disposed so as to be in close proximity to or in contact with the first main surface portion 40 of the first plate-shaped portion 31.

[0068] The second cross beams 56A and 56B are formed with second insertion holes 58. The second insertion holes 58 are arranged at positions overlapping with the first insertion holes 42 formed in the first plate-shaped portion 31 when viewed from the thickness direction of the panel body 30. The second cross beams 56A and 56B are provided with female threads corresponding to the second insertion holes 58. In the example shown in the figure, nuts are provided on the inside of the second cross beams 56A and 56B (see Figs. 13 and 14). It is to be noted that the present invention is not limited to providing nuts, and a female thread may be formed on the inner peripheral surface of the second insertion hole 58. A male thread of a screw inserted into the first insertion hole 42 is screwed into the female thread.

[0069] As described above, the first main surface portion 40 has through holes 43 formed therein. In the illustrated example, the first main surface portion 40 is a punched steel having a plurality of through holes 43 formed therein. In the illustrated example, the entire sound-absorbing material 33 constitutes the sound-absorbing portion. For example, the sound-absorbing material 33 is a porous material such as glass wool, urethane sponge, or polyester fiber. The form of the sound-absorbing material 33 is not limited to the above and can be changed according to the design specifications.

[0070] In the illustrated example, the entire second main surface portion 50 constitutes the sound insulation portion. In the illustrated example, a sheet-like glass wool (one example of the sound absorbing material 33) is attached to the sound insulation surface 50a of the second main surface portion 50 arranged on the inside of the booth. For example, the second main surface portion 50 is a steel plate without a through hole. For example, when a user in the booth faces the inclined edge portion of the top plate (for example, the right front edge portion 12e1 of the basic booth side top plate 12) and uses the work surface of the top plate, the sound generated by the user passes through the through hole 43 of the first plate-shaped portion 31 and is absorbed by the sound absorbing material 33 constituting the sound absorbing portion. Note that the sound insulation surface of the second main surface portion 50 arranged on the outside of the booth (the surface on the side where the glass wool is not attached) also has a sound insulation function.

[0071] <Connecting panels> Fig. 6 is a perspective view showing an example of attaching the second plate-shaped portion 32 of the first embodiment. Fig. 7 is a perspective view showing an example of connecting panels of the first embodiment at upper corners. Fig. 8 is a perspective view showing an example of connecting panels of the first embodiment at lower corners. Fig. 9 is a top view showing a connecting portion of the panels of the first embodiment. Fig. 10 is a perspective view showing an example of engaging the engaging claws 57 of the second plate-shaped portion 32 of the first embodiment. 6 to 10, an example of connecting panels together will be described.

[0072] For example, the panels are connected to each other at their first plate-like portions 31 via L-shaped brackets 60 that are L-shaped in plan view. In the following explanation, an example will be given in which the first plate-like portions 31 of the first panel 15 and the third panel 17 adjacent to each other in the basic booth 2 are connected to each other via the L-shaped brackets 60. The connection manner of the first panel 15 and the second panel 16 adjacent to each other in the basic booth 2, and the front panel 25 and the side panel 26 constituting the extension booth 3 (specifically, the plate-like portions on the inside of the booth are connected to each other with L-shaped metal fittings, and the engagement claws of the plate-like portions on the outside of the booth are inserted into the engagement holes of the plate-like portions on the inside of the booth) is similar to the connection manner of the first panel 15 and the third panel 17, and therefore a description thereof will be omitted.

[0073] In the illustrated example, the first plate-like portions 31 of the first panel 15 and the third panel 17 are connected to each other at two locations, an upper corner and a lower corner, via an L-shaped bracket 60. The L-shaped bracket 60 includes a first straight portion 61 extending linearly so as to overlap with the outer end portions of the first cross beams 46A, 46B of the first panel 15 in a plan view, a second straight portion 62 extending linearly so as to overlap with the outer end portions of the first cross beams 46A, 46B of the third panel 17 in a plan view, and an L-shaped portion 63 that is L-shaped in a plan view and connects the first straight portion 61 and the second straight portion 62.

[0074] At least one bolt hole 64 (two in the illustrated example) is formed in each of the first straight portion 61 and the second straight portion 62. The bolt hole 64 is arranged at a position overlapping with an outer hole 46h formed in the outer end portion of the first cross beams 46A, 46B in a plan view. The outer end portion of the first cross beams 46A, 46B is provided with a female thread (not shown) corresponding to each outer hole 46h. For example, a nut may be provided on the inside of the outer end portion of the first cross beams 46A, 46B. For example, a female thread may be formed on the inner peripheral surface of the outer hole 46h in the outer end portion of the first cross beams 46A, 46B. A male thread of a bolt 65 inserted through the outer hole 46h is screwed into the female thread.

[0075] For example, first, the first plate-shaped portions 31 of the first panel 15 and the third panel 17 are arranged in an L-shape in a plan view. Next, an L-shaped bracket 60 is arranged at each of the upper corners and lower corners of the first plate-shaped portions 31 of the first panel 15 and the third panel 17 such that the first straight portion 61 overlaps with the outer end portions of the first cross beams 46A, 46B of the first panel 15 in a plan view, and the second straight portion 62 overlaps with the outer end portions of the first cross beams 46A, 46B of the third panel 17 in a plan view. Next, a bolt 65 is inserted through the bolt hole 64 of each L-shaped bracket 60, and then screwed into a female thread (not shown) formed in the outer end portion of each of the first cross beams 46A, 46B.

[0076] For example, at the upper corners of the first plate-shaped portions 31 of the first panel 15 and the third panel 17, the bolts 65 are inserted from below into the bolt holes 64 of the L-shaped brackets 60, and then screwed into the female threads (not shown) formed in the outer end portions of the first cross beams 46A (see FIG. 7). For example, at the lower corners of the first plate-shaped portions 31 of the first panel 15 and the third panel 17, the bolts 65 are inserted from above into the bolt holes 64 of the L-shaped brackets 60, and then screwed into the female threads (not shown) formed in the outer end portions of the first cross beams 46B (see FIG. 8). In this way, the first plate-shaped portions 31 of the first panel 15 and the third panel 17 can be fixed to each other by the L-shaped brackets 60 and the bolts 65. The fixing manner of each of the first plate-shaped portions 31 of the first panel 15 and the third panel 17 (e.g., the location and number of the L-shaped brackets 60, and the location and number of the outer holes 46h) is not limited to the above and can be changed according to the design specifications.

[0077] As described above, the second vertical rods 55A, 55B of the second plate-shaped portion 32 are formed with the engagement claws 57 that engage with the engagement holes 45h of the first vertical rods 45A, 45B of the first plate-shaped portion 31. In the illustrated example, the engagement claws 57 include a first protruding portion 57a ​​that protrudes from the second vertical rods 55A, 55B toward the first vertical rods 45A, 45B and then extends downward, and a second protruding portion 57b that extends downward from a corner of the first protruding portion 57a ​​(see FIG. 10). For example, after the first plate-shaped portions 31 of the first panel 15 and the third panel 17 are fixed at the above-mentioned corners, the engagement claws 57 of the second plate-shaped portion 32 are inserted obliquely from above into the engagement holes 45h of the first plate-shaped portion 31 and engaged with the lower edge of the engagement holes 45h from above. At this time, the portion (corner) between the first protruding portion 57a ​​and the second protruding portion 57b of the engagement claw 57 is caught from above by the lower edge portion of the engagement hole 45h. In this manner, the second plate-shaped portion 32 can be attached to the first plate-shaped portion 31 (see FIG. 6).

[0078] <Connection between basic booth and expansion booth bodies> Fig. 11 is a perspective view showing an example of connecting the top plates of the first embodiment. Fig. 12 is a perspective view of the top plate bracket 70 of the first embodiment. Fig. 13 is a front view showing the connecting portion between the basic booth 2 and the extension booth main body 21 of the first embodiment. Fig. 14 is a front view showing the connecting portion between the top plate bracket 70 and the second panels 16 of the first embodiment. 11 to 14, an example of connecting the basic booth 2 and the extension booth main body 21 to each other will be described.

[0079] 1, the basic booth 2 and the extension booth main body 21 are not connected to each other through their panels, but are connected via a top plate which is a functional member. The extension booth side top plate 22 crosses the extension booth inner space 20 in a plan view, and connects the basic booth 2 and the extension booth main body 21 to each other. In this embodiment, the extension booth side top plate 22 connects the second panel 16 constituting the basic booth 2 to the front panel 25 and side panel 26 constituting the extension booth main body 21.

[0080] In a plan view, the portion of the extension booth side top plate 22 connected to the second panel 16 is longer from the front panel 25 than the portion of the extension booth side top plate 22 on the side of the side panel 26. In the illustrated example, the extension booth side top plate 22 is connected to the second panel 16, the front panel 25, and the side panel 26 via a top plate bracket 70 in which screw holes 71h and 72h are formed. In the illustrated example, the portion of the extension booth side top plate 22 connected to the second panel 16 is connected to the second panel 16 via a pair of front and rear top plate brackets 70. In the illustrated example, the portion of the extension booth side top plate 22 connected to the front panel 25 is connected to the front panel 25 via a pair of left and right top plate brackets 70. In the illustrated example, the portion of the extension booth side top plate 22 on the side of the side panel 26 is connected to the side panel 26 via one top plate bracket 70.

[0081] For example, the top plate bracket 70 is fixed to each of the extension booth side top plate 22, the second panel 16, the front panel 25, and the side panel 26 with fastening metal fittings such as screws. In the example shown in the figure, two top plate fastening screw holes 72h and two panel fastening screw holes 71h (four in total) are formed in each top plate bracket 70. In the example shown in the figure, the top plate bracket 70 is formed in an L shape when viewed from the longitudinal direction (front-rear direction in FIG. 13).

[0082] The top plate bracket 70 includes a first extension portion 71 extending in a direction along the inner surface of the panel in a plan view (front-rear direction in FIG. 11), and a second extension portion 72 extending inward (widthwise inner side in FIG. 11) from both ends (front end and rear end in FIG. 11) of the first extension portion 71 so as to follow the lower surface of the extension booth side top plate 22. One top plate fixing screw hole 72h is formed in each second extension portion 72 (two in total per top plate bracket 70). One panel fixing screw hole 71h is formed on each end side of the first extension portion 71 (two in total per top plate bracket 70). In FIG. 11, the top plate bracket 70 and the like of the portion of the extension booth side top plate 22 that is connected to the front panel 25 are omitted.

[0083] For example, the top plate bracket 70 can be fixed to the extension booth side top plate 22 by inserting a screw from below into the top plate fixing screw hole 72h of each second extension portion 72 and then screwing it into a female thread (not shown) formed on the lower surface side portion of the extension booth side top plate 22. For example, the top plate bracket 70 can be fixed to each of the second panel 16 and the side panel 26 by inserting a screw 48 from the inside in the width direction into each panel fixing screw hole 71h of the first extension portion 71 and then screwing it into a female thread (not shown) formed on the inner surface side portion of each of the second panel 16 and the side panel 26 (see FIG. 11). For example, after the screw 48 is fixed, a cap 49 for hiding the head of the screw 48 may be attached.

[0084] In this way, the second panel 16 constituting the basic booth 2 and the side panel 26 constituting the extension booth main body 21 can be fixed together by the extension booth side top plate 22, the top plate bracket 70, and the screws 48. Note that the manner in which the second panel 16 and the side panel 26 are fixed together (for example, the location and number of the top plate bracket 70, and the locations and number of the screw holes 71h, 72h) is not limited to the above and can be changed according to the design specifications.

[0085] Similarly, the second panel 16 constituting the basic booth 2 and the front panel 25 constituting the extension booth main body 21 can be fixed together using the extension booth side top panel 22, top panel bracket 70, and screws (not shown) (see FIG. 9). This allows the second panel 16 constituting the basic booth 2 to be fixed together with the front panel 25 and side panel 26 constituting the extension booth main body 21.

[0086] In this embodiment, the front panel 25 has a pair of first plate-shaped portions 31 and second plate-shaped portions 32, similar to each of the first panel 15 and the third panel 17. Meanwhile, the side panel 26 has a pair of third plate-shaped portions 75 and fourth plate-shaped portions 76 that have a different structure from the front panel 25. In this embodiment, the side panel 26 has a pair of third plate-shaped portions 75 and fourth plate-shaped portions 76, similar to the second panel 16.

[0087] Hereinafter, of the pair of third plate-shaped portion 75 and fourth plate-shaped portion 76, the one positioned inside the booth when viewed from the basic booth 2 will be referred to as the "third plate-shaped portion 75", and the one positioned outside the booth when viewed from the basic booth 2 will be referred to as the "fourth plate-shaped portion 76".

[0088] In the illustrated example, the second panel 16 is disposed between a pair of plate-shaped portions 75, 76, and further includes a third cross beam 77 joined to the third plate-shaped portion 75, and a fourth cross beam 78 joined to the fourth plate-shaped portion 76. Each of the third cross beam 77 and the fourth cross beam 78 is formed to include a portion having a U-shaped cross section. Each of the third cross beam 77 and the fourth cross beam 78 is joined to each of the plate-shaped portions 75, 76 so as to form a C-shaped cross section. The third cross beam 77 and the fourth cross beam 78 are disposed so as to be close to or in contact with each other. The second panel 16 differs from each of the first panel 15 and the second panel 16 in that the second panel 16 includes the third cross beam 77 and the fourth cross beam 78.

[0089] A third through hole 75h is formed in each of the main surface portion 75A (hereinafter also referred to as the "third main surface portion 75A") of the third plate-shaped portion 75 and the third cross beam 77 at a height position corresponding to the top plate. A fourth through hole 76h is formed in each of the main surface portion 76A (hereinafter also referred to as the "fourth main surface portion 76A") of the fourth plate-shaped portion 76 and the fourth cross beam 78 at a height position corresponding to the top plate. Although not shown, a through hole for sound absorption is formed in the fourth main surface portion 76A, and the entire third main surface portion 75A constitutes a sound insulation portion. For example, glass wool is attached to the left side surface of the third main surface portion 75A (for example, a portion facing the through hole formed in the fourth main surface portion 76A).

[0090] Each of the third cross beam 77 and the fourth cross beam 78 has a female screw corresponding to each of the insertion holes 75h and 76h. In the illustrated example, nuts 77i and 78i are provided on the inside of each of the third cross beam 77 and the fourth cross beam 78 (see Figs. 13 and 14). For example, after inserting the screw 48 from the inside in the width direction into each of the panel fixing screw holes 71h of the top plate bracket 70, the screw 48 is screwed into the female screw (nut 78i provided on the inside of the fourth cross beam 78 in the illustrated example) formed on the inner surface side of each of the second panel 16 and the side panel 26. This allows the top plate bracket 70 to be fixed to the second panel 16 via the fourth cross beam 78 functioning as a reinforcing member.

[0091] In the illustrated example, second insertion holes 58 are formed in the second cross beams 56A, 56B (see FIG. 5). The second insertion holes 58 are disposed at positions overlapping with the first insertion holes 42 formed in the first plate-shaped portion 31 when viewed in the thickness direction of the panel body 30. The second cross beams 56A, 56B are provided with female threads corresponding to the second insertion holes 58.

[0092] For example, nuts (not shown) are provided on the inside of the second cross beams 56A, 56B. For example, the screws 48 are inserted from the front into the respective panel fixing screw holes 71h of the top plate bracket 70, and then screwed into the female threads (in the illustrated example, the nuts provided on the inside of the second cross beams 56A, 56B) formed on the inner surface side portion of the front panel 25. This allows the top plate bracket 70 to be fixed to the front panel 25 via the second cross beams 56A, 56B that function as reinforcing members.

[0093] <Location of sound absorbing and insulating parts> As described above, the panel body (specifically, the panel body 30 composed of a pair of plate-like portions 31, 32, and the panel body different from the panel body 30 composed of a pair of plate-like portions 75, 76) has a sound absorbing portion with sound absorbing function on one side of the inside or outside of the booth, and a sound insulating portion with sound insulating function on the other side (see FIG. 3, etc.). With reference to FIGS. 1 and 3 together, an example of the arrangement of the sound absorbing portion and the sound insulating portion will be described. In FIG. 1, the portions having the sound absorbing portion in the thickness direction of each panel body are shown by dot hatching, and the portions having the sound insulating portion are shown by white outlines.

[0094] In the basic booth 2, each of the first panel 15 and the third panel 17 has a sound absorbing part (dot-hatched part in FIG. 1) on the inside of the booth, and a sound insulating part on the outside of the booth. Each of the first panel 15 and the third panel 17 does not have a sound absorbing part on the outside of the booth from the sound insulating part. On the other hand, each of the second panel 16 and the basic booth-side inclined panel 13 in the basic booth 2 has a sound absorbing part (dot-hatched part in FIG. 1) on the outside of the booth, and a sound insulating part on the inside of the booth. Each of the second panel 16 and the basic booth-side inclined panel 13 does not have a sound absorbing part on the inside of the booth from the sound insulating part. In this embodiment, noise outside the basic booth 2 is absorbed by the sound absorbing parts of the second panel 16 and the basic booth-side inclined panel 13, so that the effect of noise on the user in the basic booth 2 can be suppressed.

[0095] In the extension booth 3, the front panel 25 has a sound absorbing section (the dot-hatched portion in FIG. 1) on the inside of the booth, and a sound insulating section on the outside of the booth. The front panel 25 does not have a sound absorbing section on the outside of the booth from the sound insulating section. On the other hand, in the extension booth 3, the side panel 26 and the extension booth-side inclined panel 23 each have a sound absorbing section (the dot-hatched portion in FIG. 1) on the outside of the booth, and a sound insulating section on the inside of the booth. The side panel 26 and the extension booth-side inclined panel 23 each do not have a sound absorbing section on the inside of the booth from the sound insulating section. In this embodiment, noise outside the extension booth 3 is absorbed by the sound absorbing sections of the side panel 26 and the extension booth-side inclined panel 23, so that the effect of noise on the user in the extension booth 3 can be suppressed.

[0096] <Action and effect> As described above, the booth 2 of the embodiment includes the first panel 15 and the second panel 16 connected to each other. In the booth 2, the first work space 10 is formed by the first panel 15 and the second panel 16. The first panel 15 has a sound absorbing part with a sound absorbing function on the inside of the booth facing the work space 10, and has a sound insulating part with a sound insulating function on the outside of the booth opposite to the inside of the booth. The second panel 16 is connected to one end of the first panel 15 in the extending direction in a plan view, and extends in a direction perpendicular to the extending direction of the first panel in a plan view. The second panel 16 has a sound absorbing part on the outside of the booth, and has a sound insulating part on the inside of the booth. According to this configuration, when a user in the booth 2 faces the first panel 15, the sound emitted by the user is absorbed by the sound absorbing section of the first panel 15, thereby suppressing sound leakage outside the booth 2. On the other hand, when the ears of the user in the booth 2 are located on the side of the second panel 16, noise outside the booth 2 is absorbed by the sound absorbing section of the second panel 16, thereby suppressing the effect of noise on the user in the booth 2. Therefore, with the minimum necessary sound absorption and sound insulation functions according to the environment inside and outside the booth 2, sound leakage from inside the booth 2 to the outside and sound entering from the outside to inside the booth 2 can be reduced.

[0097] In the above embodiment, the booth 2 further includes a third panel 17 that is connected to the other end of the first panel 15 in the extending direction in a plan view and extends in a direction perpendicular to the extending direction of the first panel 15. The third panel 17 has a sound absorbing part on the inside of the booth and a sound insulating part on the outside of the booth. According to this configuration, the sound emitted by the user is absorbed by the sound absorbing portion of the third panel 17, so that sound leakage from inside the booth 2 to the outside can be suppressed.

[0098] In the above embodiment, the booth 2 further comprises, in the work space 10, a top plate 12 having an upwardly facing work surface 12a. According to this configuration, because the work space 10 has the tabletop 12, the direction in which the user faces is surrounded on three sides by the first panel 15, the second panel 16, and the third panel 17. Therefore, sound leakage from inside the booth 2 to the outside and sound entering from the outside of the booth 2 to the inside can be suitably reduced.

[0099] In the above embodiment, the top plate 12 has an inclined edge portion 12e1 on the edge opposite the first panel 15 when viewed in a plan view, which extends at an angle away from the first panel 15 as it moves toward the opposite side to the second panel 16 in the extension direction of the first panel 15. With this configuration, a user who uses the work surface 12a of the top panel 12 facing the inclined edge portion 12e1 of the top panel 12 is prompted to face the corner between the first panel 15 and the third panel 17, rather than directly facing the second panel 16. As a result, the sound emitted by the user is absorbed by the sound absorbing portions of the first panel 15 and the third panel 17, thereby preventing sound from leaking outside the booth 2.

[0100] The booth system 1 of the above embodiment includes a basic booth 2, which is the above-mentioned booth 2, and an extension booth 3 arranged next to the basic booth 2 with the second panel 16 in between. The extension booth 3 includes a front panel 25 arranged on one side of the front in a direction intersecting the direction in which the first panel 15 extends in a plan view, and a side panel 26 arranged on the side opposite the basic booth 2 in a plan view. With this configuration, even if a user in the extension booth 3 faces the basic booth 2 while talking, etc., the sound absorbing section on the outside of the basic booth 2 reduces sound leakage from the extension booth 3 to the basic booth 2.

[0101] In the above embodiment, the front panel 25 has a sound absorbing part on the inside of the booth facing the second work space 20 formed by the extension booth 3, and has a sound insulating part on the outside of the booth opposite the inside of the booth facing the second work space 20. The side panel 26 has a sound absorbing part on the outside of the booth opposite the inside of the booth facing the second work space 20, and has a sound insulating part on the inside of the booth facing the second work space 20. According to this configuration, when a user in the extension booth 3 faces the front panel 25, the sound emitted by the user is absorbed by the sound absorbing section of the front panel 25, thereby suppressing sound leakage outside the extension booth 3. On the other hand, when the ear of the user in the extension booth 3 is located on the side panel 26 side, noise outside the extension booth 3 is absorbed by the sound absorbing section of the side panel 26, thereby suppressing the effect of noise on the user in the extension booth 3. Therefore, with the minimum necessary sound absorption and sound insulation function according to the environment inside and outside the extension booth 3, sound leakage from inside the extension booth 3 to the outside and sound entering from the outside to inside the extension booth 3 can be reduced.

[0102] In the above embodiment, the basic booth 2 includes a top panel 12 having a work surface 12a facing upward. The top panel 12 includes an inclined edge portion 12e1 on the edge portion opposite the first panel 15 in a plan view, the inclined edge portion 12e1 extending in a direction in which the first panel 15 extends and inclines away from the first panel 15 as it moves toward the opposite side to the second panel 16. According to this configuration, when a user in the basic booth 2 faces the first panel 15, the sound emitted by the user is absorbed by the sound absorbing portion of the first panel 15, so that sound leakage to the outside of the basic booth 2 can be suppressed. On the other hand, when the ears of the user in the basic booth 2 are located on the side of the second panel 16, the noise outside the basic booth 2 is absorbed by the sound absorbing portion of the second panel 16, so that the influence of the noise on the user in the basic booth 2 can be suppressed. In addition, a user who uses the work surface 12a of the top plate 12 facing the inclined edge portion 12e1 of the top plate 12 does not face the second panel 16, so that sound leakage from the basic booth 2 to the extension booth 3 can be suppressed. Therefore, sound leakage from the inside of the basic booth 2 to the outside and sound intrusion from the outside of the basic booth 2 to the inside can be reduced with the minimum necessary sound absorbing and sound blocking functions according to the environment inside and outside the basic booth 2.

[0103] In the above embodiment, the extension booth 3 includes a top panel 22 having a work surface 22a facing upward. The top panel 22 includes an inclined edge 22e1 on the edge opposite the front panel 25 in a plan view, the inclined edge 22e1 extending in a direction in which the front panel 25 extends so as to be inclined away from the front panel 25 as it moves toward the opposite side of the side panel 26. With this configuration, a user who uses the work surface 22a of the top panel 22 facing the inclined edge 22e1 of the top panel 22 in the extension booth 3 is prompted to face the corner between the front panel 25 and the second panel 16, rather than directly facing the side panel 26. As a result, sound emitted by the user in the extension booth 3 is absorbed by the sound absorbing parts of the front panel 25 and the second panel 16, so sound leakage from the extension booth 3 to the basic booth 2 can be suppressed.

[0104] <Second embodiment> FIG. 15 is a top view of the booth 202 of the second embodiment. A second embodiment of the present invention will be described below with reference to Fig. 15. In the above-mentioned first embodiment, a configuration in which one extension booth main body 21 is connected to a basic booth 2 (see Fig. 1, etc.) has been described as an example of a booth system 1. In contrast, the second embodiment differs from the first embodiment in that it is composed of only a booth 202, as shown in Fig. 15. In the second embodiment, detailed description of components similar to those in the first embodiment will be omitted.

[0105] As described above, the panel body (specifically, the panel body 30 composed of a pair of plate-like portions 31, 32, and the panel body different from the panel body 30 composed of a pair of plate-like portions 75, 76) has a sound absorbing portion with sound absorbing function on one side of the inside or outside of the booth, and a sound insulating portion with sound insulating function on the other side (see FIG. 3, etc.). In FIG. 15, the portions having the sound absorbing portion in the thickness direction of each panel body are shown by dot hatching, and the portions having the sound insulating portion are shown by white outlines.

[0106] The booth 202 has a similar configuration to the booth 2 of the first embodiment, and therefore a detailed description thereof will be omitted. In the booth 202, each of the first panel 15 and the third panel 17 has a sound absorbing part (a dot-hatched part in FIG. 15) on the inside of the booth, and a sound insulating part on the outside of the booth. Each of the first panel 15 and the third panel 17 does not have a sound absorbing part on the outside of the booth from the sound insulating part. On the other hand, each of the second panel 16 and the basic booth-side inclined panel 13 in the booth 202 has a sound absorbing part (a dot-hatched part in FIG. 15) on the outside of the booth, and a sound insulating part on the inside of the booth. Each of the second panel 16 and the basic booth-side inclined panel 13 does not have a sound absorbing part on the inside of the booth from the sound insulating part. In this embodiment, noise outside the booth 202 is absorbed by the sound absorbing parts of the second panel 16 and the basic booth-side inclined panel 13, so that the influence of noise on the user in the booth 202 can be suppressed.

[0107] <Action and effect> As described above, the booth 202 of the second embodiment includes the first panel 15 and the second panel 16 connected to each other. In the booth 202, the work space 10 is formed by the first panel 15 and the second panel 16. The first panel 15 has a sound absorbing portion having a sound absorbing function on the inside of the booth facing the work space 10, and has a sound insulating portion having a sound insulating function on the outside of the booth opposite to the inside of the booth. The second panel 16 is connected to one end of the first panel 15 in the extending direction in a plan view, and extends in a direction perpendicular to the extending direction of the first panel 15 in a plan view. The second panel 16 has a sound absorbing portion on the outside of the booth, and has a sound insulating portion on the inside of the booth. According to this configuration, when a user in the booth 202 faces the first panel 15, sound emitted by the user is absorbed by the sound absorbing portion of the first panel 15, thereby suppressing sound leakage to the outside of the booth 202. On the other hand, when the ears of the user in the booth 202 are located on the side of the second panel 16, noise outside the booth 202 is absorbed by the sound absorbing portion of the second panel 16, thereby suppressing the effect of noise on the user in the booth 202. Therefore, with the minimum necessary sound absorption and sound insulation function according to the environment inside and outside the booth 202, sound leakage from inside the booth 202 to the outside and sound entering from the outside of the booth 202 into the inside of the booth 202 can be reduced.

[0108] According to the configuration of the embodiment described above, it is possible to reduce sound leakage from inside the booth to the outside and sound entering from the outside to the inside of the booth with the minimum necessary sound absorption and sound insulation functions according to the environment inside and outside the booth, without providing sound absorption functions on both the inside and outside of each panel. Therefore, it is possible to reduce the parts and processing costs for providing sound absorption functions, and to achieve cost reduction.

[0109] <Modification> In the above embodiment, the second panel is connected to one end of the first panel in the extending direction in a plan view and extends in a direction perpendicular to the extending direction of the first panel, but the present invention is not limited to this. For example, the second panel may extend in a direction that obliquely intersects with the extending direction of the first panel in a plan view. For example, the manner in which the second panel intersects with the first panel in a plan view can be changed according to the design specifications.

[0110] In the above embodiment, the booth further includes a top plate having a work surface facing upward. However, the present invention is not limited to this. For example, the booth does not need to include a top plate. For example, the installation mode of the top plate can be changed according to the design specifications.

[0111] In the above embodiment, the top plate is provided with an inclined edge portion on the edge portion opposite the first panel in a plan view, which inclines and extends away from the first panel as it moves toward the opposite side of the second panel in the extension direction of the first panel, but this is not limited thereto. For example, the top plate may not have an inclined edge portion. For example, the top plate may have a portion on the edge portion opposite the first panel in a plan view that extends parallel to the extension direction of the first panel. For example, the top plate may have a portion on the edge portion opposite the first panel in a plan view that inclines and extends away from the first panel as it moves toward the second panel in the extension direction of the first panel. For example, the installation mode of the inclined edge portion can be changed according to the design specifications.

[0112] In the above embodiment, an example has been described in which the booth further includes a third panel that is connected to the other end of the first panel in the extending direction in a plan view and extends in a direction perpendicular to the extending direction of the first panel, but this is not limited thereto. For example, the third panel may extend in a direction that obliquely intersects with the extending direction of the first panel in a plan view. For example, the booth may not further include a third panel. For example, the booth may only include a first panel and a second panel that are connected to each other. For example, the installation mode of the third panel may be changed according to the design specifications.

[0113] In the above embodiment, an example has been described in which the third panel has a sound absorbing part on the inside of the booth, a sound insulating part on the outside of the booth, and no sound absorbing part on the outside of the booth beyond the sound insulating part, but this is not limited thereto. For example, the third panel may have a sound absorbing part on the outside of the booth, and a sound insulating part on the inside of the booth. For example, the third panel may have a sound absorbing part on the outside of the booth beyond the sound insulating part. For example, the installation mode of the sound absorbing part and the sound insulating part in the third panel can be changed according to the design specifications.

[0114] In the above embodiment, the second panel is configured from a panel having a structure different from that of the first panel and the third panel (specifically, a pair of third and fourth plate-shaped parts), but the present invention is not limited to this. For example, the first panel, the second panel, and the third panel may each be configured from a panel having a similar structure. For example, the panel may include a rectangular panel body, a frame member arranged along the four sides of the panel body, and a leg portion provided on the frame member at the lower side and grounded on the floor surface F. The material and structure of the panel are not particularly limited, and a configuration other than those described above can be appropriately adopted. For example, the first panel, the second panel, and the third panel may be integrally formed.

[0115] In the above embodiment, the side panel is configured from a panel having a different structure from the front panel (specifically, a pair of third and fourth plate-shaped parts), but this is not limited thereto. For example, the front panel and the side panel may be configured from panels having similar structures. For example, the panel may include a rectangular panel body, a frame member arranged along the four sides of the panel body, and a leg portion provided on the frame member at the lower side and grounded on the floor surface F. The material and structure of the panel are not particularly limited, and a configuration other than those described above can be appropriately adopted. For example, the front panel and the side panel may be formed integrally.

[0116] In the above embodiment, an example was given in which sound absorbing and insulating functions were built into the panel, but this is not limited to this. For example, a separate sound absorbing panel may be attached to the booth later. For example, the form of the sound absorbing and insulating parts may be changed according to the design specifications.

[0117] In the above embodiment, an example has been described in which the booth system includes a basic booth, which is the above-mentioned booth, and an extension booth that is arranged next to the basic booth with a second panel in between, but this is not limited to the above. For example, the booth system may include multiple basic booths and not include an extension booth. For example, the booth system may include multiple extension booths and not include a basic booth. For example, the installation manner of the basic booth and the extension booth can be changed according to the design specifications.

[0118] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these, and additions, omissions, substitutions, and other modifications of the configuration are possible without departing from the spirit of the present invention, and the above-mentioned modified examples can also be combined as appropriate.
