Description

Technical Field

[0001] The present invention relates to a simple booth, and more particularly to a simple booth that can be repeatedly used as a dressing room, a nursing room, etc. in an evacuation shelter or an event venue in case of an emergency.

Background Art

[0002] Patent Document 1 discloses a folding building including a plurality of wall bodies for forming a private room space and a door body that is openably connected to one of the plurality of wall bodies. This building forms a private room space from wall bodies, a door body, a shelf body, a floor body, and a roof body, all of which are made of cardboard (paper material). On the wall body facing the wall body to which the door body is connected, a door stop portion bent into a columnar shape is formed at the position of the door stop of the door body.

[0003] Since the door stop portion is a portion where the door body contacts each time the door body is opened and closed, ensuring strength is particularly required when it is made of cardboard. The door stop portion is formed by bending it into a hollow columnar shape, for example, in a triangular shape in plan view. Thereby, the strength of the door stop portion can be improved, and the strength of the building when the door body is opened and closed can be improved. In addition, since the door stop portion is formed by bending, the building can have a simple structure.

[0004] In addition, the shelf body is used as a private room holding means for firmly maintaining the private room state of the building. The connection of the wall body, the shelf body, the floor body, and the roof body is performed by a connecting tool, and connecting holes are formed at the portions where the connecting tool is attached to the wall body, the shelf body, the floor body, and the roof body. The connecting tool is not particularly limited as long as it can fix both members.

Summary of the Invention

Problems to be Solved by the Invention

[0006] In the building described in Patent Document 1, since the door opens outward from the building, in areas where people tend to congregate, such as evacuation shelters, if sufficient space cannot be secured near the entrance of the building, it becomes difficult to open the door, and luggage cannot be placed near the outside of the building's door. Furthermore, users who leave the building step into the external space immediately after opening the door. In other words, the proximity of the building's private spaces and the public space outside the building may increase the anxiety of users using the building.

[0007] Furthermore, during the assembly of the building, shelves must be installed, columnar door stops formed, and numerous connecting devices attached to ensure the building's rigidity. This results in a complex building structure and a cumbersome assembly process, requiring a long time to complete. Moreover, the loss of even one of the numerous connecting devices makes the assembly and repeated use of the building difficult. Additionally, if tools are used to attach the connecting devices, the assembly process becomes even more complicated, and the loss of tools may also make the assembly and repeated use of the building difficult.

[0008] This invention has been made in view of these problems, and aims to provide a simple booth that is easy to assemble, rigid, safe, secure, and reusable for use as a changing room, nursing room, etc., in evacuation shelters or event venues during emergencies. [Means for solving the problem]

[0009] To achieve the above objectives, the simple booth of the present invention comprises a plurality of wall panels surrounding the sides of a private room space, a floor panel covering the lower part of the private room space, a ceiling panel covering the upper part of the private room space, and a door panel that is openably connected to one of the plurality of wall panels. In the closed state, the door panel is positioned at an inclination in plan view with respect to the front side edges of the floor panel and ceiling panel located in front of the door panel, and a front space is formed between the floor panel and the ceiling panel that protrudes in front of the door panel in the closed state. [Effects of the Invention]

[0010] Therefore, according to the present invention, it is possible to provide a simple booth that is easy to assemble, rigid, safe, secure, and reusable for use as a changing room, nursing room, etc., in evacuation shelters or event venues during emergencies. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0012] FIG. 1 shows a perspective view of the simple booth 1 according to an embodiment of the present invention as seen from the side, and FIG. 2 shows an exploded perspective view of the simple booth 1. The simple booth 1 is partitioned into a private room space 10 by a first wall panel 2A, a second wall panel 2B, a third wall panel 2C, a fourth wall panel 2D (hereinafter, also collectively referred to as each wall panel 2), a floor panel 4, a ceiling panel 6, and a door panel 8. In addition, the direction in which each panel 2 to 8 stands vertically is defined as the vertical direction Y, the width direction of each panel 2 to 8 orthogonal to the vertical direction Y is defined as the horizontal direction X, respectively, and the term of plan view (agreed with top view) used for explanation is defined as when viewing an object in a plane (horizontal plane) including the horizontal direction X.

[0013] Each wall panel 2 surrounds the side of the private room space 10. The floor panel 4 covers the lower part of the private room space 10, and the ceiling panel 6 covers the upper part of the private room space 10. The door panel 8 is a single-opening type and is connected to a first wall panel 2A, which is one of the wall panels 2, so as to be openable and closable by, for example, two hinges 12. The hinge 12 is composed of a cylindrical member 12a and a pin member 12b.

[0014] FIG. 3 shows a top view of the hinge 12. On the door panel 8, the cylindrical member 12a is pre-attached with screws 12d via brackets 12c or the like. Also, on the door connection wall portion 22 of the first wall panel 2A, a pin member 12b into which the cylindrical member 12a can be inserted is pre-attached with screws 12f via brackets 12e or the like. By lifting the door panel 8 and fitting the cylindrical member 12a into the pin member 12b from above, the door panel 8 is connected to the first wall panel 2A so as to be openable and closable.

[0015] As shown in FIGS. 1 and 2, each wall panel 2 is formed with a bent portion 14 having an L shape in plan view. Each bent portion 14 forms a booth corner portion 16 on the side of the private room space 10. The bending angle of the bent portion 14 forming the booth corner portion 16 is about 90 degrees. In addition, on the first wall panel 2A, another bent portion 14 is formed adjacent to the side of the door panel 8 of the bent portion 14 forming the booth corner portion 16, and the bending angle of this bent portion 14 is an obtuse angle.

[0016] At least one or more ventilation openings 18 that form a gap with the floor panel 4 and the ceiling panel 6 are cut out at least at one of the upper end and the lower end of at least one of the wall panels 2. The number of ventilation openings 18 may be, for example, three at each of the upper end and the lower end as shown in FIG. 1, or one at each of the upper end and the lower end as shown in FIG. 2. Also, the ventilation opening 18 has a height in the vertical direction Y of 30 mm or less and a width in the horizontal direction X of 50 mm or less.

[0017] Each adjacent wall panel 2 is joined via a connecting member 20 extending in the vertical direction Y. The connecting member 20 is positioned between adjacent booth corners 16 in a plan view of the simple booth 1. On both sides of the closed door panel 8 in the horizontal direction X, a door connecting wall portion 22 is formed, which is bent via a bend 14 in the first wall panel 2A and to which the door panel 8 is connected, and a door contact wall portion 24 is formed, which is bent via a bend 14 in the fourth wall panel 2D and to which the closed door panel 8 makes contact.

[0018] Panel edge members 26 extending in the vertical direction Y are attached to the side edges of the door connecting wall 22 and the side edges of the door contact wall 24. Door edge members 28 extending in the vertical direction Y are attached to the side edge of the door panel 8 on the side that may come into contact with the door contact wall 24. In addition, a door lock 30 is attached to the door panel 8 approximately in the vertical direction Y and near the door contact wall 24 in the horizontal direction X.

[0019] Figure 4 shows a top view of the door lock 30. The door lock 30 is a slide lock type and has a locking member 30a that can slide in the lateral direction X. By sliding the locking member 30a to a position where it overlaps with the door wall portion 24 in a plan view, the closed door panel 8 is locked in a way that prevents it from being opened within the private room space 10.

[0020] Figure 5 shows a perspective view of the lower corner of the door panel 8. Although not shown in Figures 1 and 2, a protective cap member 32 may be attached to the lower corner of the door panel 8. This prevents injury to the user if their toes or other body parts come into contact with the lower corner of the door panel 8 when opening or closing the door panel 8.

[0021] Figure 6 shows an example cross-sectional view of each panel 2 to 8. Each panel 2 to 8 is a lightweight plate member, a plastic board molded from a resin such as polypropylene. Each panel 2 to 8 is a plastic board composed of, for example, a sheet base material 34 in which numerous cylindrical recesses 34a are molded into a resin sheet, and a pair of resin covering sheets 36 that cover the front and back surfaces of the sheet base material 34, respectively. Each covering sheet 36 is bonded to the front and back surfaces of the sheet base material 34 by heat welding or the like.

[0022] Figure 7 shows a perspective view from above of the temporary booth 1 with the ceiling panel 6 removed. When the door panel 8 is closed, it is positioned at an angle in plan view to the front edges of the floor panel 4 and the ceiling panel 6, which are located in front of the door panel 8. In Figure 7, only the front edge of the floor panel 4 is shown as 4a, while the front edge of the ceiling panel 6 is shown as 6a in Figure 8, which will be described later.

[0023] Furthermore, a front space 38 is formed between the floor panel 4 and the ceiling panel 6, protruding in front of the door panel 8 when it is closed. In this embodiment, the private room space 10 has a trapezoidal shape in plan view, the floor panel 4 and ceiling panel 6 have a rectangular shape in plan view, and the front space 38 has a triangular shape in plan view.

[0024] Figure 8 shows the state when a user enters the simple booth 1. Because a front space 38 is formed in the simple booth 1, when a user opens the door panel 8, the user can enter the private room space 10 with most of the door panel 8 remaining in the front space 38. In other words, it is not necessary to open the door panel 8 wide to the outside of the simple booth 1. The user can also safely place their belongings in the front space 38. Furthermore, the front space 38 functions as a buffer space between the private room space 10, i.e., the private space, and the public space which is the outside space of the simple booth 1.

[0025] Figure 9 shows plan views of the individual room space 10 as seen from the side, for (a) ceiling panel 6, (b) floor panel 4, (c) door panel 8, (d) first wall panel 2A, (e) second wall panel 2B, (f) third wall panel 2C, and (g) fourth wall panel 2D. Each wall panel 2 has a fold line 40 extending in the vertical direction Y, with the thickness reduced by forming a groove or making a cut. Each wall panel 2 can be easily bent along the fold line 40, and by bending each wall panel 2 along the fold line 40, the aforementioned bent portion 14 is formed.

[0026] One or more protruding portions 42 are formed at the upper and lower ends of each wall panel 2. One or more fitting holes 44 are formed on the outer surfaces of each floor panel 4 and ceiling panel 6, into which the protruding portions 42 are fitted. Each wall panel 2, floor panel 4, and ceiling panel 6 are fixed together at fitting portions 45 (see Figure 1) formed by the protruding portions 42 and fitting holes 44.

[0027] Furthermore, the corners formed at the boundaries between each wall panel 2 and the floor panel 4 and ceiling panel 6 are fixed from the inside of the private room space 10 with a first-face fastener 46. The first-face fastener 46 is composed of a loop material made by forming a large number of resin fibers into a loop shape and a hook material made by fraying a large number of resin fibers. By attaching the loop material to the hook material, the loop-shaped fibers become entangled with the frayed fibers, locking the hook material and the loop material together, and enabling fixing by the first-face fastener 46.

[0028] One or more pairs of loop and hook members are pre-attached at appropriate positions where corners are formed between each wall panel 2, floor panel 4, and ceiling panel 6. In Figure 9, the loop and hook members are collectively shown as the first-face fastener 46 (the same applies to the second-face fastener 48 and third-face fastener 50, which will be described later). One of the loop and hook members has a length that allows it to be attached to the other loop and hook member.

[0029] Furthermore, it is preferable that one of the loop material and the hook material is pre-bent into an L-shape in the assembled state of the simple booth 1, in the direction along the floor panel 4 and ceiling panel 6, or each wall panel 2. Also, the fastening with the first face fastener 46 is performed from the inside of the private room space 10, and it is not possible to release the fastening with the first face fastener 46 from the outside of the private room space 10. In addition, it is preferable that the first face fastener 46 be attached near the fitting portion 45, as shown in Figure 9.

[0030] In addition to being joined by the aforementioned joining member 20, adjacent wall panels 2 are also fixed from the outside of the private room space 10 with a second-face fastener 48. The second-face fastener 48 is a fixing means similar to the first-face fastener 46, and a pair of loop or hook members are pre-attached to the vicinity of the side edges of each opposing wall panel 2. Furthermore, it is preferable to attach the second-face fastener 48 to the top of each wall panel 2, as shown in Figure 9.

[0031] Figure 10 shows (a) a side view of the joining member 20, (b) a cross-sectional view of the joining member 20, (c) a side view of the door edge member 28, (d) a cross-sectional view of the door edge member 28, (e) a side view of the panel edge member 26, and (f) a cross-sectional view of the panel edge member 26. The joining member 20, the door edge member 28, and the panel edge member 26 are formed from a lightweight metal material, such as aluminum. As shown in Figure 10(b), the joining member 20 has a roughly H-shaped cross-section in the lateral direction, as shown in Figure 10(d), the door edge member 28 has a roughly T-shaped cross-section in the lateral direction, and as shown in Figure 10(f), the panel edge member 26 has a roughly U-shaped cross-section in the lateral direction.

[0032] The joining member 20 has two joining surfaces 20a to which the side edges of each opposing wall panel 2 are joined, the door edge member 28 has one joining surface 28a to which the side edge of the opposing door panel 8 is joined, and the panel edge member 26 has one joining surface 26a to which the side edges of each opposing wall panel 2 are joined. Each joining surface 20a, 28a, and 26a and the aforementioned side edges to which they are attached are fixed with a third-face fastener 50. The third-face fastener 50 is a fixing means similar to the first and second face fasteners 46 and 48.

[0033] The following describes an example of the assembly procedure for the simple booth 1, referring to Figures 11 to 16. In each figure, the parts enclosed in circles or squares with leader lines, indicated as (a), (b), (c), etc., are enlarged partial views of parts necessary for explanation. Figure 11 shows an explanatory diagram of the procedure for assembling the first wall panel 2A to the floor panel 4.

[0034] First, as shown in Figure 11, the floor panel 4 is placed, and then (a) the side edge of the first wall panel 2A and the joint surface 26a of the panel edge member 26 are brought together and fixed with a third-face fastener 50, thereby attaching the panel edge member 26 to the first wall panel 2A. (b) and (c) show the upper and lower ends of the first wall panel 2A with the panel edge member 26 attached, respectively.

[0035] Next, (d) the first wall panel 2A is bent at two curved lines 40 to form two bent sections 14 and one booth corner section 16, and then the protruding section 42 formed at the lower end of the first wall panel 2A is fitted into the fitting hole 44 of the corresponding floor panel 4, and the first wall panel 2A is assembled to the floor panel 4. Next, (e) the first wall panel 2A and the floor panel 4 are fixed together with two first-sided fasteners 46.

[0036] Figure 12 shows an explanatory diagram of the procedure for assembling the second wall panel 2B to the floor panel 4. Next, as shown in Figure 12, (a) the side edge of the second wall panel 2B and one of the joining surfaces 20a of the joining member 20 are brought together and fixed with a third-face fastener 50, thereby attaching the joining member 20 to the second wall panel 2B. Next, (b) the second wall panel 2B is bent along one of the fold lines 40 to form the bent portion 14 and the booth corner portion 16. Next, the other joining surface 20a of the joining member 20 attached to the second wall panel 2B is brought together with the side edge of the first wall panel 2A and fixed with a third-face fastener 50.

[0037] At the same time, the protruding portion 42 formed at the lower end of the second wall panel 2B is fitted into the fitting hole 44 of the corresponding floor panel 4, and the second wall panel 2B is assembled to the floor panel 4. Next, (c) the second wall panel 2B and the floor panel 4 are fixed together with two first-sided fasteners 46. Next, (d) the first and second wall panels 2A and 2B are fixed together with second-sided fasteners 48.

[0038] Figure 13 shows an explanatory diagram of the procedure for assembling the third wall panel 2C to the floor panel 4. Next, as shown in Figure 13, (a) the side edge of the third wall panel 2C and one of the joining surfaces 20a of the joining member 20 are brought together and fixed with a third-face fastener 50, thereby attaching the joining member 20 to the third wall panel 2C. Next, (b) the third wall panel 2C is bent along one of the fold lines 40 to form the bent portion 14 and the booth corner portion 16. Next, the other joining surface 20a of the joining member 20 attached to the third wall panel 2C is brought together with the side edge of the second wall panel 2B and fixed with a third-face fastener 50.

[0039] At the same time, the protruding portion 42 formed at the lower end of the third wall panel 2C is fitted into the fitting hole 44 of the corresponding floor panel 4, and the third wall panel 2C is assembled to the floor panel 4. Next, (c) the third wall panel 2C and the floor panel 4 are fixed together with two first-sided fasteners 46. Next, (d) the second and third wall panels 2B and 2C are fixed together with second-sided fasteners 48.

[0040] Figure 14 shows an explanatory diagram of the procedure for assembling the fourth wall panel 2D to the floor panel 4. Next, as shown in Figure 14, (a) the side edge of the fourth wall panel 2D and one of the joining surfaces 20a of the joining member 20 are brought together and fixed with the third-face fastener 50, thereby attaching the joining member 20 to the fourth wall panel 2D. Next, (b) the side edge of the fourth wall panel 2D and the joining surface 26a of the panel edge member 26 are brought together and fixed with the third-face fastener 50, thereby attaching the panel edge member 26 to the fourth wall panel 2D. Next, (c) the fourth wall panel 2D is bent at one of the fold lines 40 to form the bent portion 14 and the booth corner portion 16.

[0041] Next, the other joint surface 20a of the joint member 20 attached to the fourth wall panel 2D is abutted against the side edge of the third wall panel 2C and fixed with the third-face fastener 50. At the same time, the protruding portion 42 formed at the lower end of the fourth wall panel 2D is fitted into the fitting hole 44 of the corresponding floor panel 4, and the fourth wall panel 2D is assembled to the floor panel 4. Next, (d) the fourth wall panel and the floor panel are fixed together with a first-face fastener 46 at one location. Next, (e) the third and fourth wall panels 2C and 2D are fixed together with the second-face fastener 48.

[0042] Figure 15 shows an explanatory diagram of the procedure for assembling the ceiling panel 6 to each wall panel 2. Next, as shown in Figure 15, the ceiling panel 6 is placed on top of each assembled wall panel 2. At this time, the fitting holes 44 of the ceiling panel 6 are fitted into the protruding portions 42 formed at the upper end of each wall panel 2, and the ceiling panel 6 is assembled to each wall panel 2. It is preferable to fit the fitting holes 44 into the protruding portions 42 sequentially along the circumferential direction of the simple booth 1, starting from the side of the door connecting wall portion 22 or the door stop wall portion 24. This allows the ceiling panel 6 to be supported by the door connecting wall portion 22 or the door stop wall portion 24 during the installation work of the ceiling panel 6. Therefore, the ceiling panel 6 can be assembled in a stable state, and the efficiency of the assembly work of the simple booth 1 can be improved.

[0043] Next, (a) each wall panel 2 and the ceiling panel 6 are fixed together with the respective first-face fasteners 46. When sequentially fitting the fitting holes 44 into the protruding portions 42, it is preferable to temporarily fasten the first-face fasteners 46 near the fitted locations. This allows the ceiling panel 6 to be assembled in a more stable state, thereby further improving the efficiency of the assembly work of the simple booth 1. After fitting the fitting holes 44 into all the protruding portions 42, the temporarily fastened first-face fasteners 46 are permanently fastened to secure them.

[0044] Figure 16 shows an explanatory diagram of the procedure for assembling the door panel 8 to the first wall panel 2A. Next, as shown in Figure 16, (a) the side edge of the door panel 8 and the joining surface 28a of the door edge member 28 are butted together and fixed with the third-face fastener 50, thereby attaching the door edge member 28 to the door panel 8. Next, (b) the protective cap member 32 is attached to the lower end corner of the door edge member 28 from below by bonding it with the included adhesive or the like. Next, the door panel 8 is lifted, and the cylindrical member 12a of the door panel 8 is fitted onto the pin member 12b of the door connecting wall 22 from above, thereby attaching the door panel 8 to the door connecting wall 22. With these steps, the assembly of the simple booth is complete.

[0045] Figure 17 shows a schematic perspective view of the simple booth 1 when it is disassembled and ready for packaging. In its packaged state, the simple booth 1 has a compact shape, for example, a length L of approximately 2220 mm, a width W of approximately 1250 mm, and a height H of approximately 380 mm. Furthermore, each wall panel 2 has a hollow laminated structure as shown in Figure 6, and is lightweight, so the simple booth 1 can be easily transported to evacuation shelters and other locations.

[0046] As described above, in this embodiment, the simple booth 1 is positioned at an inclination in plan view with respect to the front side edges 4a and 6a of the floor panel 4 and ceiling panel 6, respectively, which are located in front of the door panel 8 when the door panel 8 is closed, and a front space 38 is formed between the floor panel 4 and the ceiling panel 6. This makes it possible to realize a simple booth 1 that is easy to assemble, rigid, safe and secure, and can be used repeatedly as a changing room or nursing room in an evacuation shelter or event venue in times of emergency.

[0047] Specifically, the user can enter the private room 10 by opening the door panel 8 in the front space 38. The user can also safely place their belongings in the front space 38. Furthermore, by creating a buffer space between the private room 10, i.e., the private space, and the public space which is the external space of the simple booth 1, the user's sense of security when using the simple booth 1 can be enhanced.

[0048] More specifically, the private room space 10 has a trapezoidal shape in plan view, the floor panel 4 and ceiling panel 6 have a rectangular shape in plan view, and the front space 38 has a triangular shape in plan view. This makes it possible to form the front space 38 while keeping the simple booth 1 in a relatively simple shape.

[0049] Furthermore, each wall panel 2 has a bent portion 14 formed on it, and each bent portion 14 forms a booth corner 16. This makes it possible to form seamless booth corners 16 in the simple booth 1 with the simple operation of just bending each wall panel 2. Consequently, the rigidity of the simple booth 1, especially in the vertical direction Y, can be increased.

[0050] Furthermore, on both sides of the closed door panel 8 in the lateral direction X, a door connecting wall portion 22 and a door stop wall portion 24 are formed, which are bent via a bending portion 14. This makes it possible to make the door connecting wall portion 22 and the door stop wall portion 24 seamless from the booth corner portion 16. Consequently, the rigidity of the door connecting wall portion 22 and the door stop wall portion 24, which are prone to load due to the opening and closing of the door panel 8, can be increased.

[0051] Furthermore, each wall panel 2 has a fold line 40 extending in the vertical direction Y, with the thickness reduced accordingly. By bending each wall panel 2 along the fold line 40, a bent portion 14 and a booth corner portion 16 are formed on each wall panel 2. This allows for the formation of the bent portion 14 and booth corner portion 16 on each wall panel 2 with simple processing and work.

[0052] Furthermore, one or more protrusions 42 are formed at the upper and lower ends of each wall panel 2, and one or more fitting holes 44 are formed on the outer surfaces of each floor panel 4 and ceiling panel 6, into which the protrusions 42 are fitted. Each wall panel 2, floor panel 4, and ceiling panel 6 are fixed together at fitting portions 45 formed by the protrusions 42 and fitting holes 44. As a result, screws or other fasteners for fixing each wall panel 2, floor panel 4, and ceiling panel 6, and tools for attaching the fasteners are not required.

[0053] Furthermore, since the protruding portion 42 and the fitting hole 44 are pre-formed at predetermined locations, the positioning of each wall panel 2 relative to the floor panel 4 and ceiling panel 6 becomes easier during operation. Therefore, the rigidity of the simple booth 1 can be increased by fitting, while the assembly work of the simple booth 1 can be simplified. Since the assembly and disassembly of the simple booth 1 can be completed in a short time, repeated use of the simple booth 1 is also easy.

[0054] Furthermore, the corners formed at the boundaries between each wall panel 2 and the floor panel 4 and ceiling panel 6 are fixed from the inside of the private room space 10 with first-face fasteners 46. This allows the fitting portion 45 to be reinforced with the first-face fasteners 46, thereby simplifying the assembly of the simple booth 1 while further increasing its rigidity. The reinforcing effect of the first-face fasteners 46 on the fitting portion 45 can be further improved by attaching the first-face fasteners 46 near the fitting portion 45. In addition, since the fixing by the first-face fasteners 46 cannot be released from the outside of the private room space 10, the sense of security for users of the simple booth 1 can be further enhanced.

[0055] Furthermore, adjacent wall panels 2 are joined via connecting members 20 that extend in the vertical direction Y and have a roughly H-shaped cross-section in the horizontal direction X. This allows the connection between adjacent wall panels 2 to be reinforced by the connecting members 20, thereby further increasing the rigidity of the simple booth 1, especially in the vertical direction Y.

[0056] Furthermore, each adjacent wall panel 2 is fixed with a second-sided fastener 48. This further reinforces the connection between adjacent wall panels 2 with the second-sided fastener 48, thereby simplifying the assembly of the simple booth 1 while increasing its rigidity, particularly in the lateral X direction. The reinforcing effect of the second-sided fastener 48 on the connection between each wall panel 2 is further improved by attaching the second-sided fastener 48 to the upper part of the simple booth 1, which tends to be unstable, i.e., the upper part of each wall panel 2.

[0057] Furthermore, panel edge members 26 extending in the vertical direction Y are attached to the side edges of the door connecting wall 22 and the door contact wall 24, respectively. In addition, door edge members 28 extending in the vertical direction Y are attached to the side edge of the door panel 8 on the side that may come into contact with the door contact wall 24. This makes it possible to increase the rigidity of the door connecting wall 22, the door contact wall 24, and the door panel 8, which are particularly susceptible to load when the door panel 8 is opened and closed, especially in the vertical direction Y.

[0058] Furthermore, the joining member 20, panel edge member 26, and door edge member 28 are fixed to each side edge of the wall panel 2, door connecting wall section 22, door stop wall section 24, and door panel 8 to which they are attached, respectively, by the third-sided fastener 50. This simplifies the assembly of the simple booth 1 using the third-sided fastener 50, while also providing a more robust fixation between the joining member 20, panel edge member 26, and door edge member 28 and the aforementioned side edges.

[0059] Furthermore, at least one ventilation opening 18 is cut out from the upper and lower ends of at least one of the wall panels 2, forming a gap with the floor panel 4 and the ceiling panel 6. By forming the ventilation openings 18, the ventilation of the private room space 10 can be improved. The ventilation openings 18 have a vertical height of 30 mm or less and a horizontal width of 50 mm or less. As a result, it is not possible to insert a smartphone or the like into the ventilation openings 18, so the inside of the private room space 10 cannot be photographed by a smartphone camera. Therefore, the sense of security of users using the simple booth 1 can be further enhanced.

[0060] Furthermore, the simple booth 1 is equipped with a door lock 30 that locks the closed door panel 8 from the inside of the private room space 10, preventing it from being opened or closed. As a result, when a user uses the simple booth 1, they can lock the door panel 8 with the door lock 30, making it impossible to open the door panel 8 from the outside of the private room space 10. Therefore, the sense of security for users of the simple booth 1 can be further enhanced.

[0061] Furthermore, each panel 2 to 8 is a plastic board composed of the aforementioned sheet base material 34 and each covering sheet 36. By making each panel 2 to 8 such a hollow laminated structure, it is possible to reduce the weight of each panel 2 to 8 while increasing both their flexibility and strength. Therefore, the packaged temporary booth 1 can be easily transported to evacuation centers, etc., and the rigidity of the temporary booth 1 can be increased while the assembly work of the temporary booth 1 can be made easier.

[0062] This concludes the description of one embodiment of the present invention. However, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the invention. For example, the front space 38 is not limited to the shape described, as long as it is possible to form the front space 38. Also, each panel 2 to 8 is not strictly limited to the plastic board of the structure described above.

[0063] Furthermore, if it is possible to form a front space 38, the door panel 8 may open to the right or to the left. In addition, the simple booth 1 of the present invention can be repeatedly used as a changing room or nursing room in evacuation shelters or event venues in times of emergency, but it can also be used for various other purposes. For example, a toilet can be installed in the private room space 10 to create a private room space 10 where even greater privacy is required. The simple booth 1 can also be used for remote meetings or as a concentration booth when one wants to concentrate on work. [Explanation of Symbols]
