Description

[Technical Field]

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

[0002] In offices, exhibition halls, public facilities, etc., booths are sometimes set up for work. In particular, in recent years, with the trend toward free address systems in offices and the advancement of mobile work utilizing ICT (information and communication technology) such as mobile devices and personal computers, there are an increasing number of opportunities to use small booths to perform work at various locations.

[0003] The booth has a plate-shaped ceiling wall with a downward-facing ceiling surface, and cylindrical side walls extending downward from the periphery of the ceiling surface. The booth has an interior space surrounded by the ceiling wall and side walls. In the booths described in Patent Documents 1 and 2, the ceiling wall is constructed by arranging multiple planar members in a direction along the ceiling surface. Because the ceiling wall is constructed from multiple planar members, even if the size of the ceiling wall increases as the booth becomes larger, the ceiling wall can be easily transported to the installation location of the booth in a state where it is divided into multiple planar members. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2022-142688 [Patent Document 2] Japanese Patent Publication No. 2022-007394 Summary of the Invention [Problem to be solved by the invention]

[0005] When installing this type of booth, the cylindrical side walls are assembled, and then the ceiling wall is installed above the side walls. When installing the ceiling wall above the side walls, for example, it is possible to place multiple planar members individually on the upper side of the side walls from the outside, and then assemble the multiple planar members into a single unit to form the ceiling wall. However, when placing the planar members on the upper side of the side walls from the outside, a sufficient working space of height is required above the side walls. Therefore, if the ceiling height of the room in which the booth is installed is low, the working space above the side walls will be low, making it difficult to install the planar members (ceiling wall) above the side walls.

[0006] The present invention has been made in consideration of the above circumstances, and aims to provide a booth in which planar members can be easily installed on the upper side of the side wall even if the height of the work space above the side wall is low. [Means for solving the problem]

[0007] (1) A first aspect of the booth according to the present invention comprises a plate-shaped ceiling wall having a ceiling surface facing downward, and a cylindrical side wall extending downward from the periphery of the ceiling wall, and has an internal space surrounded by the ceiling wall and the side wall, the ceiling wall having a plurality of planar members arranged in a direction along the ceiling surface, the plurality of planar members having a specific planar member, an opening surrounded by other components of the ceiling wall excluding the specific planar member, or an opening surrounded by the other components and the side wall, which is an insertion opening for inserting the specific planar member from the internal space side, and at least a portion of the periphery of the insertion opening is a placement portion for placing a portion of the specific planar member.

[0008] In the booth according to the first aspect, the specific planar member can be inserted through the insertion opening from the interior space side, moved to the upper side of the insertion opening, and then placed on the placement section formed by the peripheral edge of the insertion opening. By placing the specific planar member at the upper end of the side wall in this way, the specific planar member can be easily placed at the upper end of the side wall even if the height of the work space above the side wall is low. Furthermore, since there is no need to place the specific planar member on top of the side wall from the outside of the side wall, it is possible to position at least a portion of the side wall close to the wall (indoor wall) of the room in which the booth is installed.

[0009] (2) A second aspect of the booth of the present invention is that, in the first aspect, the placement portion has a first placement portion and a second placement portion positioned at a distance from each other in the circumferential direction of the peripheral portion, and the specific planar member may be bridged between the first placement portion and the second placement portion.

[0010] In a booth configured in this manner, the specific planar member can be placed on the two placement sections formed from the peripheral edges of the insertion opening, for example, by the following procedure. First, the specific planar member is placed in the internal space so that both ends of the specific planar member placed on the two mounting sections are aligned in the direction of the arrangement of the two mounting sections. Next, one end of the specific planar member is passed from the internal space through the insertion opening and positioned above one of the mounting sections. In this state, the other end of the specific planar member is positioned in the internal space.

[0011] From this state, the specific planar member is moved slightly in the direction from the other mounting portion toward one of the mounting portions, so that the other end of the specific planar member located in the internal space is positioned between the two mounting portions, i.e., below the insertion opening. Then, the other end of the specific planar member is passed from the internal space through the insertion opening and placed on the upper side of the other mounting portion. Finally, one end of the specific planar member is placed on the upper side of one of the mounting portions. This allows the specific planar member to be placed on the two mounting portions. In this manner, the specific planar member can be easily installed on the upper end of the side wall from the interior space side.

[0012] (3) A third aspect of the booth according to the present invention may be such that, in the second aspect, an entrance / exit is provided in a circumferential portion of the side wall, and the first and second loading sections are arranged at intervals along the ceiling surface in the opening direction of the entrance / exit.

[0013] In a booth configured in this way, the specific planar member can be placed on the two mounting sections in the interior space through the entrance with both ends of the specific planar member aligned in the direction of the two mounting sections, and can be placed on the two mounting sections in the same manner as described above without changing the orientation of the specific planar member in the interior space. This makes it even easier to install the specific planar member on the upper end of the side wall from the interior space side.

[0014] (4) A fourth aspect of the booth according to the present invention is that, in the third aspect, the specific planar members may be arranged in multiple rows along the ceiling surface in a direction intersecting the arrangement direction of the first and second placement sections.

[0015] In a booth configured in this manner, the ceiling wall is composed of multiple specific planar members lined up in a direction (intersecting direction) that intersects the arrangement direction of the two mounting sections. Therefore, the dimensions (width) of each specific planar member in the intersecting direction can be made smaller than the width of the ceiling wall in the intersecting direction. This allows specific planar members to be easily introduced into the interior space through the entrance with both ends of the specific planar members placed on the two mounting sections aligned in the arrangement direction of the two mounting sections, even if the width of the entrance is small in the intersecting direction.

[0016] (5) A fifth aspect of the booth according to the present invention is that, in the third or fourth aspect, the first loading section is located between the second loading section and the entrance / exit in the opening direction, and the other planar members among the plurality of planar members, excluding the specific planar member, may include a front side member removably arranged between the first loading section and the upper end of the side wall where the entrance / exit is located.

[0017] In booths with entrances and exits, users enter and exit the internal space through the entrance, so a space (external space) large enough for users and other people to pass through is secured outside the entrance. For this reason, in the above configuration, the front side surface member located on the entrance side does not need to be attached and detached to the upper side of the side wall through the internal space like the specific planar member, but can be attached and detached from the outside of the side wall (external space side). By removing the front side member located between the first placement section and the upper end of the side wall where the entrance is located, an opening appears between the first placement section and the upper end of the side wall. This allows access from the interior space to the specific planar member located behind the first placement section (toward the second placement section) through the opening. For example, the opening makes it easy to handle the electrical wiring of electrical components such as lighting units and fans provided on the specific planar member.

[0018] (6) A sixth aspect of the booth of the present invention may be any one of the first to fifth aspects, and may further include a connection receiving member provided at the end of the specific planar member placed on the placement portion, and a connecting member connected to the connection receiving member from the underside of the placement portion through the placement portion and the end of the specific planar member.

[0019] In a booth configured in this manner, the specific planar member can be connected and fixed to the mounting portion from inside the booth (the interior space side), which means that the specific planar member can be placed and fixed to the mounting portion from inside the booth (the interior space side).

[0020] (7) A seventh aspect of the booth of the present invention is any one of the first to sixth aspects, in which the specific planar member may have a central planar member that includes the central portion of the ceiling wall when viewed from above the side wall.

[0021] In a booth configured in this manner, the central portion of the ceiling wall is included in a single central planar member, so there are no connection points between planar members in the central portion of the ceiling wall. Therefore, simply by installing items such as a fire extinguisher or lighting unit on the central planar member located in the central portion of the ceiling wall, the items can be easily placed in the central portion of the ceiling wall. Furthermore, by installing the fire extinguisher in the central portion of the ceiling wall, the fire extinguisher can be used to efficiently extinguish fires in the interior space. Furthermore, by installing the lighting unit in the central portion of the ceiling wall, the lighting unit's light can be used to uniformly illuminate the interior space.

[0022] (8) In an eighth aspect of the booth according to the present invention, in the seventh aspect, electrical equipment may be provided on the central planar member.

[0023] In a booth configured in this manner, electrical equipment such as lighting units and fans are mounted on a single central planar member, making it easy to handle the electrical wiring extending from the electrical equipment (wiring work).

[0024] (9) A ninth aspect of the booth of the present invention is any one of aspects 1 to 8, in which the specific planar member has a planar shape having multiple corners when viewed from the thickness direction of the plate, and the insertion opening when viewed from the top of the side wall has the same shape and size as the planar shape of the specific planar member.

[0025] In a booth configured in this manner, the planar shapes of the specific planar member and the insertion opening both have multiple corners, so that even if the planar shapes and sizes of the specific planar member and the insertion opening are the same, the specific planar member can be passed from the internal space through the insertion opening. The insertion opening can then be covered by the specific planar member. [Effects of the Invention]

[0026] According to the present invention, the appearance design of the booth as viewed from the outside can be improved. [Brief explanation of the drawings]

[0028] An embodiment of the present invention will be described below with reference to Figures 1 to 11. In the following description, expressions indicating relative or absolute arrangement, such as "parallel," "orthogonal," and "center," not only strictly indicate such arrangement, but also indicate 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.

[0029] The booth 1 of this embodiment shown in Figure 1 is installed on the floor of an office, public institution, etc., and has an internal space K1 that is isolated from the outside of the booth 1 (hereinafter referred to as the external space) and is used for carrying out work, etc.

[0030] As shown in FIG. 1, the booth 1 includes a floor 2, side walls 3, a ceiling wall 4, and a door 5. The floor 2, side walls 3, and ceiling wall 4 are arranged in this order from the bottom up. In this embodiment, the direction in which the floor 2, side walls 3, and ceiling wall 4 are arranged is referred to as the vertical direction Z. In addition, in the drawing, the side toward which the arrow in the vertical direction Z points (+Z side) is referred to as the "upper side," and the side opposite the side toward which the arrow in the Z direction points (-Z side) is referred to as the "lower side."

[0031] The floor section 2 is formed in a roughly plate-like shape and is placed on the floor surface on which the booth 1 is to be installed. Although not shown, a plurality of casters and a plurality of height-adjustable adjusters are arranged at appropriate positions on the underside of the floor section 2. The casters are provided so that they can come into contact with the floor surface, and by rolling, the entire booth 1 can be easily moved. Furthermore, by bringing the adjusters into contact with the floor surface, the casters are separated from the floor surface, restricting the movement of the booth 1. In this embodiment, the planar shape of the floor portion 2 when viewed from the plate thickness direction is rectangular. However, the planar shape of the floor portion 2 may be any shape, such as a circle.

[0032] 1 and 2, the side wall 3 is formed in a cylindrical shape extending upward from the periphery of the floor portion 2. An entrance / exit 6 that connects the internal space K1 of the booth 1 to the external space is provided at a part of the periphery of the side wall 3.

[0033] In this embodiment, the direction in which users of the booth 1 enter and exit between the internal space K1 and the external space through the entrance / exit 6 is defined as the front-to-rear direction Y. Furthermore, in the drawings, the side toward which the arrow of the front-to-rear direction Y points (+Y side) is defined as the "rear side," and the side opposite to the side toward which the arrow of the front-to-rear direction Y points (-Y side) is defined as the "front side." Note that the front side (-Y side) is the direction in which users of the booth 1 exit from the internal space K1 to the external space through the entrance / exit 6. The front-to-rear direction Y is perpendicular to the up-to-down direction Z. In this embodiment, the direction perpendicular to the up-down direction Z and the front-rear direction Y is defined as the left-right direction X (width direction X). Furthermore, in the drawings, the side toward which the arrow of the left-right direction X points (+X side) is defined as the "left side," and the side opposite to the side toward which the arrow of the left-right direction X points (-X side) is defined as the "right side." The right side (-X side) corresponds to the right-hand side of a user of booth 1 facing forward (-Y side).

[0034] The side wall 3 of this embodiment has four flat wall portions extending along each of the four sides of the floor portion 2, which is rectangular in plan view. The four wall portions include a front wall portion 31 located at the front side of the booth 1, a rear wall portion 32 located at the rear side of the booth 1, a left wall portion 33 located at the left side of the booth 1, and a right wall portion 34 located at the right side of the booth 1.

[0035] The aforementioned entrance 6 is provided in the front wall 31. In this embodiment, the entrance 6 is located in the middle of the front wall 31 in the left-right direction X. The height dimension of the entrance 6 in the up-down direction Z is approximately the same as the height dimension of the front wall 31. Therefore, the front wall 31 is located on both sides of the entrance 6 in the left-right direction X.

[0036] The door 5 is attached so as to be able to open and close the above-mentioned entrance 6. The door 5 of this embodiment is attached so as to be able to rotate about an axis extending in the vertical direction Z at the left end of the entrance 6. When the door 5 closes the entrance 6, the door 5 and the front wall 31 appear to be formed integrally. In the illustrated example, when the door 5 closes the entrance 6, the door 5 and the front wall 31 appear to form a single flat plate. Note that the door 5 only needs to be attached so as to be able to at least open and close the entrance 6, and the specific shape and attachment manner of the door 5 may be any.

[0037] As shown in Figures 1 and 5, in this embodiment, the front wall 31, the rear wall 32, and the door 5 are formed to be light-transmittable. On the other hand, the left wall 33 and the right wall 34 are wall portions that do not transmit light. Therefore, the internal space K1 can be seen from the external space (outside the booth 1) through the front wall 31 and the rear wall 32. Furthermore, even if the entrance / exit 6 is closed by the door 5, the internal space K1 can also be seen from the external space through the door 5. The internal space K1 cannot be seen from the external space through the left wall 33 and the right wall 34.

[0038] 1 to 4, the ceiling wall 4 covers the opening at the upper end of the side wall 3. In other words, the ceiling wall 4 has a ceiling surface 4a facing downward, and the cylindrical side wall 3 extends downward from the periphery of the ceiling surface 4a. As a result, the booth 1 has an internal space K1 surrounded by the ceiling wall 4 and the side wall 3. In this embodiment, the ceiling surface 4a extends in a direction (front-rear direction Y, left-right direction X) perpendicular to the up-down direction Z.

[0039] The ceiling wall 4 has a plurality of planar members 40 arranged in a direction along the ceiling surface 4a. The ceiling wall 4 of this embodiment also has beams 41 that span the upper ends of the side walls 3. These plurality of planar members 40 and beams 41 can be placed individually on the upper sides of the side walls 3 when the ceiling wall 4 is provided on the upper sides of the side walls 3.

[0040] The multiple planar members 40 include specific planar members 42, 43, and 44 and other planar members 45. In this embodiment, the specific planar members 42, 43, and 44 are members that can be placed on the upper side of the side wall 3 from the internal space K1 side through an insertion opening 10 located at the upper end of the side wall 3. At least a portion of the peripheral portion of the insertion opening 10 forms a placement portion 8 on which a portion of the specific planar members 42, 43, and 44 are placed. The other planar member 45 is a member that is placed on the upper side of the side wall 3 from outside the side wall 3 in the external space of the booth 1. Note that the other planar member 45 may also be a member that can be placed on the upper side of the side wall 3 through an insertion opening, similar to the specific planar members 42, 43, and 44, for example.

[0041] The aforementioned insertion opening 10 is a component of the booth 1 that opens from the internal space K1 side to the upper side of the side wall 3. In this embodiment, the insertion opening 10 is configured as an opening 10 surrounded by the other components of the ceiling wall 4, excluding the specific planar members 42, 43, and 44, and the side wall 3. The other components of the ceiling wall 4 may be other planar members 45, beams 41, etc.

[0042] In this embodiment, the mounting portion 8, which is formed on the periphery of the insertion opening 10, has a first mounting portion 81 and a second mounting portion 82 that are spaced apart in the circumferential direction of the periphery. The specific planar members 42, 43, 44 are bridged between the first mounting portion 81 and the second mounting portion 82.

[0043] The specific configuration of the ceiling wall 4 of this embodiment will be described below. The ceiling wall 4 of this embodiment is located at the rear end of the booth 1 and has a central planar member 42, a left planar member 43, and a right planar member 44 aligned in the left-right direction X, a front side surface member 45 located at the front end of the booth 1, and a beam 41 located between the central planar member 42, the left side planar member 43, and the right side planar member 44 and the front side surface member 45. The central planar member 42, the left side planar member 43, and the right side planar member 44 are the specific planar members 42, 43, and 44 described above, and the front side surface member 45 is the other planar member 45 described above.

[0044] The central planar member 42, the left planar member 43, the right planar member 44, and the front side planar member 45 all have a shape in plan view that has multiple corners when viewed in their plate thickness direction (vertical direction Z). Specifically, the central planar member 42, the left planar member 43, the right planar member 44, and the front side planar member 45 are all formed in a rectangular shape having two sides extending in the left-right direction X and two sides extending in the front-rear direction Y.

[0045] The central planar member 42, the left planar member 43, and the right planar member 44 are all rectangular in shape, with the dimension in the front-to-rear direction Y being longer than the dimension in the left-to-right direction X. The dimensions in the front-to-rear direction Y of the central planar member 42, the left planar member 43, and the right planar member 44 are equal to one another. The total dimension in the left-to-right direction X of the central planar member 42, the left planar member 43, and the right planar member 44, which are lined up without any gaps in the left-to-right direction X, is approximately equal to the dimension in the left-to-right direction X of the side wall 3.

[0046] The central planar member 42 is located in the middle of the booth 1 in the left-right direction X. The central planar member 42 also includes the central portion of the ceiling wall 4 when viewed from above the side wall 3. The central portion of the ceiling wall 4 is a portion of the ceiling wall 4 that is a predetermined distance inside the side wall 3 when viewed from above the side wall 3. The left planar member 43 is located to the left of the central planar member 42, and the right planar member 44 is located to the right of the central planar member 42.

[0047] The front side surface member 45 has a rectangular shape with a dimension in the left-right direction X longer than a dimension in the front-rear direction Y. The dimension of the front side surface member 45 in the left-right direction X is approximately equal to the dimension of the side wall 3 in the left-right direction X. The dimension of the front-rear direction Y of the front side surface member 45 is shorter than the dimensions of the central planar member 42, the left side surface member 43, and the right side surface member 44 in the front-rear direction Y. Therefore, an area of ​​the opening at the upper end of the side wall 3 that is larger than the rear half is covered by the central planar member 42, the left side surface member 43, and the right side surface member 44. In addition, an area of ​​the opening at the upper end of the side wall 3 that is smaller than the front half is covered by the front side surface member 45.

[0048] The beam 41 is a rod-shaped member that extends linearly. Both longitudinal ends of the beam 41 are fixed to the upper ends of the side walls 3, and the beam 41 is suspended over the internal space K1. Specifically, the beam 41 is suspended over the internal space K1 so as to extend in the left-right direction X. The beam 41 divides the opening at the upper end of the side wall 3 into an opening 10 behind the beam 41 and an opening 20 in front of the beam 41 (see FIG. 6). The beam 41 supports the front ends of the central, left and right planar members 42, 43 and 44, and the rear end of the front side member 45 from below (see FIG. 3).

[0049] As shown in Figures 1 to 4, the insertion opening 10 through which the specific planar members 42, 43, 44, namely the central planar member 42, the left planar member 43, and the right planar member 44, are inserted from the internal space K1 side is composed of an opening 10 surrounded by a beam 41 (another component of the ceiling wall 4) and a portion of the side wall 3 located rearward of the beam 41, when viewed from above the side wall 3.

[0050] The central planar member 42, the left planar member 43, and the right planar member 44 are each bridged between a first placement portion 81 and a second placement portion 82 that are spaced apart in the front-to-rear direction Y (the opening direction of the entrance / exit 6) in the peripheral portion of the insertion opening 10. The first placement portion 81 is formed by the beam 41. The second placement portion 82 is formed by the upper end portion of the rear wall portion 32 (side wall 3). Therefore, the first placement portion 81 is located between the front wall portion 31 (entrance / exit 6) and the second placement portion 82 (rear wall portion 32) in the front-to-rear direction Y.

[0051] The central planar member 42 is placed only on the first placement portion 81 and the second placement portion 82. Although not shown, the left side planar member 43 and the right side planar member 44 are placed on the first placement portion 81 and the second placement portion 82, similar to the central planar member 42. The left side planar member 43 is also placed on the left end portion of the central planar member 42 and the upper end portion of the left wall portion 33. The right side planar member 44 is also placed on the right end portion of the central planar member 42 and the upper end portion of the right wall portion 34.

[0052] The central planar member 42, the left planar member 43 and the right planar member 44 placed as described above cover the entire insertion opening 10. The insertion opening 10 can be divided into a first split insertion opening 11 covered by the central planar member 42, a second split insertion opening 12 covered by the left planar member 43, and a third split insertion opening 13 covered by the right planar member 44. When viewed from the top of the side wall 3, the shape and size of the first split insertion opening 11 are the same as the shape and size of the central planar member 42 in a plan view. That is, when viewed from the top of the side wall 3, the first split insertion opening 11 is a rectangle (a shape with multiple corners) of the same size as the central planar member 42. Similarly, when viewed from the top of the side wall 3, the shape and size of the second split insertion opening 12 are the same as the shape and size of the left planar member 43 in a plan view. Furthermore, when viewed from the top of the side wall 3, the shape and size of the third split insertion opening 13 are the same as the shape and size of the right planar member 44 in a plan view. Note that "the same shape" and "the same size" do not necessarily mean "completely the same" but may also mean "slightly different."

[0053] The front side surface-like member 45 is placed on the peripheral portion of the opening 20 surrounded by the beam 41 and the portion of the side wall 3 located forward of the beam 41. Specifically, the rear end of the front side surface-like member 45 is placed on the beam 41, and the front end of the front side surface-like member 45 is placed on the upper end of the front wall portion 31. Although not shown, the left end of the front side surface-like member 45 is placed on the upper end of the left wall portion 33, and the right end of the front side surface-like member 45 is placed on the upper end of the right wall portion 34. The rear end of the front side surface-like member 45 is placed on the beam 41 via the front end of the central planar member 42. By placing the front side surface member 45 in this manner, the opening 20 located on the front side of the beam 41 is covered.

[0054] Next, an example of a manner in which the plurality of planar members 40 placed as described above are fixed will be described. The front and rear ends of the central planar member 42 placed on the beam 41 (first mounting portion 81) and the upper end (second mounting portion 82) of the rear wall 32 may be fixed to the upper ends of the beam 41 and the rear wall 32 from the internal space K1 side, for example. For example, connecting members such as bolts may be passed through the upper ends of the beam 41 and the rear wall 32 from the bottom (internal space K1 side) and then screwed into connecting receiving members such as connecting receiving nuts provided on the front and rear ends of the central planar member 42, thereby fixing the central planar member 42 to the upper ends of the beam 41 and the rear wall 32. This allows the central planar member 42 to be detachably attached to the upper side of the side wall 3.

[0055] The front and rear ends of the left and right planar members 43, 44 may be fixed to the upper ends of the beam 41 and the rear wall 32, similarly to the central planar member 42 described above. Similarly, the left end of the left planar member 43 and the right end of the right planar member 44 may also be fixed to the upper ends of the left and right wall 33, 34. The right end of the left side surface member 43 may be fixed to the left end of the central surface member 42 by passing a connecting member such as a bolt from the internal space K1 side, or by passing a connecting member above the left side surface member 43 and the central surface member 42 in the direction in which the left side surface member 43 and the central surface member 42 are aligned (left-right direction X).

[0056] The left end of the right side surface member 44 may be fixed to the right end of the central surface member 42 by passing a connecting member from the internal space K1 side, or by passing a connecting member above the right side surface member 44 and the central surface member 42 in the direction in which the right side surface member 44 and the central surface member 42 are aligned (left-right direction X). This allows the left side surface member 43 and the right side surface member 44 to be detachably attached to the upper side of the side wall 3.

[0057] The front end of the front side surface-like member 45 may be fixed to the upper end of the front wall 31 by passing a connecting member from the internal space K1 side. The left and right ends of the front side surface-like member 45 may be fixed to the upper ends of the left wall 33 and the right wall 34 by passing a connecting member from the internal space K1 side. The rear end of the front side surface-like member 45 may be fixed to the front end of the beam 41 or the central planar member 42 by passing a connecting member from the internal space K1 side, or may be fixed by passing a connecting member above the front side surface-like member 45 and the central planar member 42 in the direction in which the front side surface-like member 45 and the central planar member 42 are aligned (the front-to-rear direction Y). This allows the front side surface-like member 45 to be detachably attached to the upper side of the side wall 3.

[0058] Although not shown, the ceiling wall 4 also has a plate-shaped ceiling cover that covers the upper sides of the above-mentioned multiple planar members 40. The ceiling cover may be composed of, for example, multiple separate plate-shaped members. The ceiling cover may be simply placed on the upper sides of the multiple planar members 40, or may be fixed to the multiple planar members 40 or the side wall 3 with connecting members such as bolts.

[0059] As shown in FIG. 1 , electrical components 101, 102 are provided on the central planar member 42 of this embodiment. The electrical components 101, 102 include a lighting unit 101 and a fan 102. The lighting unit 101 irradiates light toward the internal space K1. The fan 102 flows air to allow air to flow in and out between the internal space K1 and the external space. That is, the fan 102 may, for example, exhaust air from the internal space K1 to the external space, or supply air from the external space into the internal space K1.

[0060] Furthermore, a fire extinguisher 103 is detachably attached to the central planar member 42 of this embodiment. The fire extinguisher 103 is provided on the ceiling surface 4a side of the ceiling wall 4, and sprays a fire extinguishing agent into the internal space K1 when a fire is detected. In the illustrated example, two fire extinguishers 103 are attached to the central planar member 42, but the number of fire extinguishers 103 may be any number.

[0061] Next, an example of a method for assembling the booth 1 of this embodiment will be described mainly with reference to FIGS. In assembling the booth 1, first, the side walls 3 are provided above the floor 2 as shown in Fig. 5. Then, the ceiling wall 4 is provided above the side walls 3 as shown in Figs.

[0062] When providing the ceiling wall 4, first, as shown in Fig. 6, a beam 41 is attached to the upper end of the side wall 3. The beam 41 may be introduced into the internal space K1 through the entrance 6, for example, and placed on the upper end of the side wall 3 from the internal space K1 side, and then fixed to the upper end of the side wall 3 with connecting members such as bolts. In this embodiment, both ends of the beam 41 are fixed to the left wall portion 33 and the right wall portion 34 so that the beam 41 extends in the left-right direction X. In addition, the beam 41 is positioned closer to the front than the middle of the side wall 3 in the front-rear direction Y. With the beam 41 attached, the opening at the upper end of the side wall 3 is divided into an opening 10 behind the beam 41 and an opening 20 in front of the beam 41. The opening 10 behind the beam 41 functions as an insertion opening 10 through which the specific planar members 42, 43, 44, that is, the central planar member 42, the left planar member 43, and the right planar member 44 (see FIGS. 7 and 10), are inserted from the internal space K1 side.

[0063] 7, a portion of the central planar member 42 is placed on the mounting portion 8, which is part of the peripheral portion of the insertion opening 10. Specifically, the front end portion of the central planar member 42 in the front-to-rear direction Y is placed on the beam 41, which is the first mounting portion 81, and the rear end portion of the central planar member 42 in the front-to-rear direction Y is placed on the upper end portion of the rear wall portion 32, which is the second mounting portion 82.

[0064] The central planar member 42 can be placed on the upper ends of the two mounting portions 81, 82, that is, the beam 41 and the rear wall portion 32, for example, in the following manner. First, the front end and rear end of the central planar member 42 are lined up in order toward the rear (+Y side), and then the central planar member 42 is placed into the internal space K1 through the entrance 6. At this time, the entire central planar member 42 may enter the internal space K1, or only the portion of the central planar member 42 on the front end side may enter the internal space K1.

[0065] 8, the front end of the central planar member 42 is passed from the internal space K1 through the insertion opening 10 and positioned above the rear wall 32 (second mounting portion 82). In this state, the rear end of the central planar member 42 is positioned in the internal space K1. Then, the central planar member 42 is moved slightly rearward (in the direction from the beam 41 toward the rear wall 32) to position the front end of the central planar member 42 between the two mounting portions 81, 82, i.e., below the insertion opening 10. 9, the rear end of the central planar member 42 is passed from the internal space K1 through the insertion opening 10 and placed on the upper side of the beam 41 (first placement portion 81). Finally, the front end of the central planar member 42 is placed on the upper side of the rear wall portion 32. As a result of the above, the central planar member 42 is placed on the upper end portions of the beam 41 and the rear wall portion 32.

[0066] 7, after the central planar member 42 is placed, the central planar member 42 covers only the middle portion of the insertion opening 10 in the left-right direction X (i.e., the first split insertion opening 11). The portions on both sides of the insertion opening 10 that are not covered by the central planar member 42 in the left-right direction X (i.e., the second and third split insertion openings 12, 13) are covered by the left planar member 43 and the right planar member 44. After the central planar member 42 is placed, the central planar member 42 is fixed to the upper end of the beam 41 and the rear wall portion 32 by connecting members such as bolts.

[0067] 10, after the central planar member 42 is fixed, a portion of the left side planar member 43 and a portion of the right side planar member 44 are placed on the placement portions 8 that are part of the peripheral portion of the insertion opening 10. Specifically, similar to the central planar member 42 described above, the front ends of the left side planar member 43 and the right side planar member 44 in the front-to-rear direction Y are placed on the beam 41 that is the first placement portion 81, and the rear ends of the left side planar member 43 and the right side planar member 44 in the front-to-rear direction Y are placed on the upper end of the rear wall portion 32 that is the second placement portion 82. When placing the left side surface member 43, both ends of the left side surface member 43 in the left-right direction X are also placed on the upper end of the left wall portion 33 and the left end of the central planar member 42. When placing the right side surface member 44, both ends of the right side surface member 44 in the left-right direction X are also placed on the upper end of the right wall portion 34 and the right end of the central planar member 42.

[0068] The procedure for placing the left side surface member 43 and the right side surface member 44 on the upper ends of the beam 41 and the rear wall portion 32 may be the same as the procedure for placing the central surface member 42. Here, the planar shape of the left side surface member 43 and the planar shape of the first split insertion opening 11 through which the left side surface member 43 is inserted are the same shape and size, but the planar shape of the left side surface member 43 is rectangular (having multiple corners). Therefore, as in the case of the central surface member 42, the left side surface member 43 can be inserted into the first split insertion opening 11 from the internal space K1 side. This is also true for the right side surface member 44.

[0069] After the left side surface member 43 and the right side surface member 44 are placed, they are fixed to the upper ends of the beam 41 and the rear wall 32 with connecting members such as bolts. The left side surface member 43 is also fixed to the upper ends of the central planar member 42 and the left wall 33 with connecting members. The right side surface member 44 is also fixed to the upper ends of the central planar member 42 and the right wall 34 with connecting members.

[0070] After the left side surface member 43 and the right side surface member 44 are fixed, as shown in FIG. 11, the peripheral portion of the front side surface member 45 is placed on the peripheral portion of the opening 20 on the front side of the beam 41. Specifically, the rear end portion of the front side surface member 45 is placed on the beam 41, and the front end portion of the front side surface member 45 is placed on the upper end portion of the front wall portion 31. Furthermore, the left end portion of the front side surface member 45 is placed on the upper end portion of the left wall portion 33, and the right end portion of the front side surface member 45 is placed on the upper end portion of the right wall portion 34. Note that the front end portion of the central planar member 42 is interposed between the rear end portion of the front side surface member 45 and the beam 41 (see FIG. 3). In this embodiment, the front side surface member 45 is placed on the upper side of the side wall 3 from the external space located in front of the entrance 6 (front wall portion 31) and placed as described above.

[0071] After the front side surface member 45 is placed, it is fixed to the upper ends of the beam 41 and the front wall 31 by connecting members such as bolts. The front side surface member 45 is also fixed to the upper ends of the left wall 33 and the right wall 34 by connecting members. The front side surface member 45 is also fixed to the front ends of the central plate member 42, the left plate member 43, and the right plate member 44 by connecting members. The fixing of the rear end of the front side surface member 45 to the front ends of the central, left side surface member 43, and right side surface member 44 by the connecting members may be performed, for example, by accessing from the side of the internal space K1, or, for example, by accessing the upper side of the side wall from the front side of the front wall portion 31 where the entrance / exit 6 is located. Note that, because there is sufficient space (external space) outside the entrance / exit 6 for users and others to pass through when entering and exiting the booth 1, it is possible to access the upper side of the side wall from the front side of the front wall portion 31.

[0072] Then, by placing a ceiling cover (not shown) on the above-mentioned plurality of planar members 40, the installation of the ceiling wall 4 on the upper side of the side wall 3 is completed. 1, the door 5 is attached to the entrance 6, thereby completing the assembly method of the booth 1. Note that the ceiling cover may be installed after the door 5 is attached, for example.

[0073] In the above-described method of assembling the booth 1, the front side surface member 45 may be inserted, for example, from the internal space K1 side through the front opening 20 of the beam 41 and then placed on the upper side of the side wall 3. Therefore, the front side surface member 45 may be the specific planar member of the present invention. Also, the front opening 20 of the beam 41 may function as the insertion opening of the present invention.

[0074] As described above, the booth 1 of this embodiment has an insertion opening 10 provided at the upper end of the side wall 3, through which the specific planar members 42, 43, 44 (the central planar member 42, the left planar member 43, and the right planar member 44) of the multiple planar members 40 are inserted from the internal space K1 side. Therefore, the specific planar members 42, 43, 44 can be inserted from the internal space K1 side through the insertion opening 10, moved to the upper side of the insertion opening 10, and then placed on the placement section 8 formed by the peripheral portion of the insertion opening 10. By installing the specific planar members 42, 43, 44 at the upper end of the side wall 3 in this manner, the specific planar members 42, 43, 44 can be easily installed at the upper end of the side wall 3 even if the height of the work space above the side wall 3 is low. Furthermore, since there is no need to place the specific planar members 42, 43, 44 on the upper side of the side wall 3 from the outside of the side wall 3, it is possible to position at least a portion of the side wall 3 close to the wall (indoor wall) of the room in which the booth 1 is installed.

[0075] Furthermore, in the booth 1 of this embodiment, the specific planar members 42, 43, 44 are bridged between a first placement portion 81 and a second placement portion 82 that are positioned at a circumferential distance from each other around the periphery of the insertion opening 10. Therefore, as described in the above-described method of assembling the booth 1, by sequentially passing both end portions (front end, rear end) of the specific planar members 42, 43, 44 placed on the two placement portions 81, 82 from the internal space K1 through the insertion opening 10, the both end portions (front end, rear end) of the specific planar members 42, 43, 44 can be easily positioned above the two placement portions 81, 82. This makes it possible to easily install the specific planar members 42, 43, 44 on the upper end of the side wall 3 from the internal space K1 side.

[0076] Furthermore, in the booth 1 of this embodiment, the first placement section 81 and the second placement section 82 are aligned at a distance from each other in the opening direction (front-rear direction Y) of the entrance 6 along the ceiling surface 4a. Therefore, by placing the specific planar members 42, 43, 44 placed on the two placement sections 81, 82 in a state where both ends of the specific planar members 42, 43, 44 are aligned in the arrangement direction of the two placement sections 81, 82, the specific planar members 42, 43, 44 can be placed on the two placement sections 81, 82 without changing the orientation of the specific planar members 42, 43, 44 in the internal space K1. This makes it even easier to install the specific planar members 42, 43, 44 on the upper end of the side wall 3 from the internal space K1 side.

[0077] Furthermore, in the booth 1 of this embodiment, the multiple specific planar members 42, 43, 44 are aligned along the ceiling surface 4a in a transverse direction (left-right direction X) that intersects with the arrangement direction of the first placement portion 81 and the second placement portion 82. Therefore, the dimension (width dimension) of each specific planar member 42, 43, 44 in the transverse direction can be made smaller than the width dimension of the ceiling wall 4 in the transverse direction. As a result, even if the width dimension of the entrance / exit 6 in the transverse direction is small, the specific planar members 42, 43, 44 can be easily introduced into the internal space K1 from the entrance / exit 6 with both ends of the specific planar members 42, 43, 44 placed on the two placement portions 81, 82 aligned in the arrangement direction of the two placement portions 81, 82.

[0078] Furthermore, in the booth 1 of this embodiment, the front side surface-like member 45 is detachably arranged between the first placement portion 81 and the upper end of the front wall portion 31 (side wall 3) where the entrance / exit 6 is located. This allows the front side surface-like member 45 to be attached and detached from the outside of the side wall 3 without having to enter or exit the internal space K1. To explain this point, in a booth 1 having an entrance / exit 6, users enter and exit the internal space K1 through the entrance / exit 6. This ensures a space (external space) outside the entrance / exit 6 large enough for users and other people to pass through. This allows the front side surface-like member 45 to be attached and detached from the outside of the side wall 3 adjacent to the entrance / exit 6.

[0079] Furthermore, when the front side surface member 45 located between the first placement portion 81 and the upper end of the front wall portion 31 is removed, an opening 20 appears between the first placement portion 81 and the upper end of the front wall portion 31 (see FIG. 10 ). This allows access from the internal space K1 through the opening 20 to the specific planar members 42, 43, 44 located rearward of the first placement portion 81 (toward the second placement portion 82). For example, the opening 20 can be used to easily handle electrical wiring (wiring work) for the electrical components 101, 102, such as the lighting unit 101 and the fan 102, provided on the central planar member 42. Furthermore, for example, the opening 20 can also be used to connect the specific planar members 42, 43, 44 adjacent to each other in the left-right direction X above the specific planar members 42, 43, 44 aligned in the left-right direction X.

[0080] Furthermore, in the booth 1 of this embodiment, the central portion of the ceiling wall 4 as seen from above the side wall 3 is included in a single central planar member 42. Therefore, there are no connection portions between the planar members 40 in the central portion of the ceiling wall 4. This makes it possible to easily position items such as a fire extinguisher 103, lighting unit 101, and fan 102 in the central planar member 42 located in the central portion of the ceiling wall 4. Note that by providing the fire extinguisher 103 in the central portion of the ceiling wall 4, the fire extinguisher 103 can efficiently extinguish a fire in the internal space K1. Furthermore, by providing the lighting unit 101 in the central portion of the ceiling wall 4, it is possible to uniformize the brightness of the internal space K1 due to the light from the lighting unit 101.

[0081] Furthermore, in the booth 1 of this embodiment, electrical components 101, 102 such as a lighting unit 101 and a fan 102 are provided on the central planar member 42. By providing the electrical components 101, 102 on the single central planar member 42, work (wiring work) handling the electrical wiring extending from the electrical components 101, 102 can be easily performed.

[0082] In addition, in the booth 1 of this embodiment, the left side surface member 43 and the right side surface member 44, which are the specific planar members 42, 43, 44, each have a shape in a plan view that has multiple corners when viewed from the plate thickness direction. Furthermore, the second and third split insertion openings 12, 13 (insertion openings) through which the left side surface member 43 and the right side surface member 44 are inserted have the same shape and size as the planar shapes of the left side surface member 43 and the right side surface member 44, respectively, when viewed from above the side wall 3. That is, the left side surface member 43 and the second split insertion opening 12 through which it is inserted both have the same shape in a plan view that has multiple corners. Similarly, the right side surface member 44 and the third split insertion opening 13 through which it is inserted both have the same shape in a plan view that has multiple corners. In this way, even though the left side surface member 43, the right side surface member 44, and the second and third split insertion openings 12, 13 have the same planar shape and size, the left side surface member 43 and the right side surface member 44 can be passed from the internal space K1 through the second and third split insertion openings 12, 13. The left side surface member 43 and the right side surface member 44 can cover the second and third split insertion openings 12, 13, respectively.

[0083] In the above embodiment, for example, the ceiling wall 4 may not include the beam 41, or the beam 41 may be formed integrally with the front side surface member 45. In this case, the rear end of the front side surface member 45 may function as a first placement portion 81 on which the front ends of the central planar member 42, the left side surface member 43, and the right side surface member 44 are placed. In this case, in the method of assembling the booth 1, after the front side surface member 45 is placed on the upper side of the side wall 3, the central planar member 42, the left side surface member 43, and the right side surface member 44 may be placed on the upper side of the side wall 3.

[0084] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be modified as appropriate within the scope of the invention.

[0085] The booth of the present invention may include a connection receiving member 91 and a connecting member 92, as shown in FIG. 12, for example. The connection receiving member 91 is provided at the end of the specific planar member 47 of the ceiling wall 4 that is placed on the mounting portion 8. The connecting member 92 is connected to the connection receiving member 91 from the underside of the mounting portion 8 through the end of the mounting portion 8 and the specific planar member 47. The connection receiving member 91 is, for example, a connection receiving nut, and the connecting member 92 is, for example, a bolt that screws into the connection receiving nut. The mounting portion 8 illustrated in FIG. 12 is the upper end portion 35 of the side wall 3. The mounting portion 8 may be, for example, another component of the ceiling wall 4 (for example, a beam or another planar member other than the specific planar member 47). Furthermore, if there are multiple mounting portions 8 on which the end portions of the specific planar member 47 are to be placed, the connection structure using the connection receiving member 91 and the connecting member 92 described above may be adopted for at least one of the mounting portions 8.

[0086] 12, the specific planar member 47 can be connected and fixed to the mounting portion 8 from inside the booth (the internal space K1 side). Therefore, both the mounting and fixing of the specific planar member 47 to the mounting portion 8 can be performed from inside the booth (the internal space K1 side).

[0087] In the present invention, the number and arrangement of the planar members 40 that make up the ceiling wall 4 are not limited to those shown in the above embodiment, and may be arbitrary. For example, as shown in FIG. 13, the multiple planar members 40 may include a left side planar member 43E, a central planar member 42E, and a right side planar member 44E that are aligned in the left-right direction X at the middle portion of the opening at the upper end of the side wall 3 in the front-to-back direction Y, and a front side planar member 45E and a rear side planar member 46E that extend in the left-to-right direction X at the front and rear of these three planar members 42E to 44E.

[0088] 13, for example, the central planar member 42E, the left planar member 43E, and the right planar member 44E may be specific planar members. In this case, the front end and the rear end of each of the central planar member 42E, the left planar member 43E, and the right planar member 44E may be placed on a first placement portion and a second placement portion aligned in the front-rear direction Y. These first placement portion and second placement portion may be formed by beams similar to those in the above embodiment, or may be formed by a front side surface member 45E and a rear side surface member 46E.

[0089] 13 , for example, an opening surrounded by planar members 43E-46E of the plurality of planar members 40 excluding one predetermined planar member, or an opening surrounded by the other planar members and the side wall 3, may function as an insertion opening for inserting the predetermined planar member from the internal space K1 side to the upper side of the side wall 3. For example, an opening 10E1 surrounded by planar members 43E-46E of the plurality of planar members 40 excluding the central planar member 42E may function as an insertion opening 10E1 for inserting the central planar member 42E from the internal space K1 side to the upper side of the side wall 3. For example, an opening 10E2 surrounded by planar members 42E-45E of the plurality of planar members 40 excluding the rear side surface member 46E and the side wall 3 may function as an insertion opening 10E2 for inserting the rear side surface member 46E from the internal space K1 side to the upper side of the side wall 3.

[0090] Furthermore, as shown in FIG. 14, for example, the multiple planar members 40 may include a rear side member 46F, a central planar member 42F, and a front side member 45F, each extending in the left-right direction X from the left wall portion 33 to the right wall portion 34 and aligned in the front-to-back direction Y. 14, for example, at least one of the rear side surface member 46F, the central planar member 42F, and the front side surface member 45F may be a specific planar member. When all of the rear side surface member 46F, the central planar member 42F, and the front side surface member 45F are specific planar members, the upper ends of the left wall portion 33 and the right wall portion 34 may function as a first mounting portion and a second mounting portion for mounting both ends of the rear side surface member 46F, the central planar member 42F, and the front side surface member 45F in the left-right direction X.

[0091] 14 , for example, an opening surrounded by the other planar members 45F, 46F of the plurality of planar members 40 excluding one predetermined planar member and the side wall 3 may function as an insertion opening for inserting the predetermined planar member from the internal space K1 side to the upper side of the side wall 3. For example, an opening 10F1 surrounded by the other planar members 45F, 46F of the plurality of planar members 40 excluding the central planar member 42F and the side wall 3 may function as an insertion opening 10F1 for inserting the central planar member 42F from the internal space K1 side to the upper side of the side wall 3. For example, an opening 10F2 surrounded by the other planar members 42F, 45F of the plurality of planar members 40 excluding the rear side surface member 46F and the side wall 3 may function as an insertion opening 10F2 for inserting the rear side surface member 46F from the internal space K1 side to the upper side of the side wall 3.

[0092] In the present invention, the two mounting portions (first mounting portion, second mounting portion) that are formed on the periphery of the insertion opening and on which the specific planar member is placed may be disposed adjacent to each other in the circumferential direction of the periphery of the insertion opening. For example, the two mounting portions may be formed by a part of the upper end portion of the left wall portion 33 and the upper end portion of the rear wall portion 32 that is continuous therewith.

[0093] In the present invention, the planar shape of the specific planar member is not limited to a polygonal shape such as a rectangle, but may be any shape having at least two corners. That is, the planar shape of the specific planar member may be, for example, a triangular, fan-shaped, or semicircular shape. Even with such a configuration, the same effects as those of the above embodiment can be achieved. That is, even if the specific planar member has a planar shape such as a fan-shaped or semicircular shape, the specific planar member can be inserted into an insertion opening of the same shape and size as the specific planar member and the insertion opening can be covered by the specific planar member.

[0094] In the present invention, the specific planar member is not limited to being placed on the upper sides of the first and second placement sections 81 and 82 by inserting it from the interior space K1 through the insertion opening and into the upper sides of the side wall 3 (or the first and second placement sections 81 and 82). For example, the specific planar member may be placed on the upper sides of the first and second placement sections 81 and 82 from an exterior space located in front of the entrance 6 (front wall section 31). This method of placing the specific planar member is particularly effective when the specific planar member is light in weight. For example, in the booth 1 of the above embodiment, this method is more effective for the left and right planar members 43 and 44, which are lighter in weight and do not have items such as a fire extinguisher, lighting unit, or fan, than for the central planar member 42, which is heavy and has items such as the fire extinguisher, lighting unit, or fan mounted thereon.

[0095] In the present invention, the booth may not have, for example, a floor portion 2. In this case, the side walls 3 of the booth may extend directly upward from the floor surface on which the booth is installed.

[0096] In the present invention, the booth may not have, for example, a door 5. That is, the entrance / exit 6 of the booth may be, for example, always open. [Explanation of symbols]
