[0018] An embodiment of the folding room of the present invention will be described below with reference to the drawings. The folding room of the present invention can be used as a changing room in an evacuation shelter or the like in the event of a disaster to protect privacy. The folding room can also be used as a food stall (temporary store) at events. In the following description, the longitudinal direction is L, the transverse direction intersecting the longitudinal direction is S, and the height direction is H. [First embodiment]

[0019] A folding room 11 of a first embodiment will be described with reference to Figures 1 to 16. As shown in Figures 1 to 3, 13, and 16, the folding room 11 includes a bottom 12 serving as a base, a plurality of legs 13 supporting the bottom 12, a top wall 14 facing the bottom 12, a side wall 15 connecting the bottom 12 and the top wall 14, a bottom wall 18 separating an internal space 16 surrounded by the top wall 14 and the side wall 15 from an underfloor space 17 on the bottom 12 side, an actuator unit 21 housed in the underfloor space 17, a control panel 22 for controlling the extension or contraction of each actuator of the actuator unit 21, a door 23 provided in a first side wall 31 of the side wall 15 to be described later and constituting an entrance and exit, and a sealing wall 24 provided in the first side wall 31 of the side wall 15 to be described later. The bottom 12, top wall 14, side wall 15, bottom wall 18, door 23, and sealing wall 24 can each be formed from, for example, an aluminum alloy, etc., to achieve weight reduction, but iron, stainless steel, resin, etc. may also be used. By combining these materials, the folding room 11 can be formed while taking into consideration strength, durability, external environment (changes due to humidity and temperature environment), and safety.

[0020] As shown in Figures 2 and 10, the legs 13 have a base 13A, casters 13B for moving the folding room 11, and a support 13C with an adjuster that allows the protruding length from the bottom 12 to be adjusted.

[0021] The bottom portion 12 is formed in a flat plate shape. The top wall portion 14 forms a roof of the folding room 11. As shown in Figures 1 to 5, the side wall portion 15 has a pair of first side wall portions 31 extending in the longitudinal direction L of the folding room 11 and a pair of second side wall portions 32 extending in a lateral direction S perpendicular to the longitudinal direction L of the folding room 11.

[0022] As shown in Figs. 1 to 3, each of the first side walls 31 is formed in a flat plate shape. The first side wall 31 includes a first panel 31A on the lower side, a second panel 31B on the upper side, a first hinge portion 31C with a gear provided between the first panel 31A and the second panel 31B, a second hinge portion 31D with a gear provided between the first panel 31A and the bottom portion 12, and a third hinge portion 31E with a gear provided between the second panel 31B and the top wall portion 14. As shown in Fig. 16, the first hinge portion 31C is provided on the outside opposite to the internal space 16 side. The second hinge portion 31D and the third hinge portion 31E are provided on the internal space 16 side.

[0023] The first panel 31A and the second panel 31B are rotatably connected by a first hinge portion 31C. The first side wall portion 31 is deformable between a first position P1 in which it is extended as shown in Fig. 16 and a second position P2 in which it is folded inward as shown in Fig. 13. The first side wall portion 31 may further have a first locking mechanism (not shown) that fixes the first panel 31A and the second panel 31B to prevent the first panel 31A and the second panel 31B from moving from the first position P1 to the second position P2.

[0024] As shown in FIG. 1 and FIG. 2, the first side wall portion 31 on the front side has a pair of doors 23. The first side wall portion 31 on the front side has a first panel 31A and a second panel 31B at a position between the pair of doors 23. As shown in FIG. 1, each of the pair of doors 23 has a door main body 23A and a frame-shaped door frame 23B surrounding the door main body 23A. The door main body 23A can be opened and closed about a pivot provided on the first panel 31A and the second panel 31B side of the door frame 23B, and in the open state, a person can enter and exit the folding room 11. The door 23 is configured to be rotatable with respect to the bottom portion 12 via a hinge. The door 23 can be rotated between an upright position S1 in which the door 23 is fixed to the first panel 31A and the second panel 31B in an upright state as shown in FIG. 1, and a horizontally laid position S2 in which the door 23 is laid horizontally so as to be folded over against the bottom wall portion 18 as shown in FIG. 11. That is, the door 23 can be laid down on its side into the interior space 16 prior to folding the folding room 11. When the door 23 is in the laid down position S2, an opening 33 is formed where the original door 23 was located.

[0025] As shown in FIG. 3, the first side wall 31 on the rear side has a pair of sealing walls 24. The first side wall 31 on the rear side has a first panel 31A and a second panel 31B between the pair of sealing walls 24. Unlike the door 23, the sealing wall 24 cannot be opened or closed. Like the door 23, the sealing wall 24 is configured to be rotatable with respect to the bottom 12 via a hinge. The sealing wall 24 can be rotated between an upright position S1 in which the sealing wall 24 is fixed to the first panel 31A and the second panel 31B in an upright state, and a lateral position S2 in which the sealing wall 24 is laid down so as to be folded over against the bottom wall 18. That is, prior to folding the folding room 11, the sealing wall 24 can be laid down toward the interior space 16. When the sealing wall 24 is in the lateral position S2, an opening 33 is formed at the location where the original sealing wall 24 was located. As shown in FIG. 11, in this laid-down state, the sealing wall 24 is disposed below the door 23, but the sealing wall 24 may be disposed above the door 23.

[0026] As shown in FIG. 1, FIG. 4, and FIG. 5, each of the second side walls 32 is formed in a flat plate shape. The second side wall 32 includes a third panel 32A on the lower side, a fourth panel 32B on the upper side, a fourth hinge portion 32C with a gear provided between the third panel 32A and the fourth panel 32B, a fifth hinge portion 32D with a gear provided between the third panel 32A and the bottom portion 12, and a sixth hinge portion 32E with a gear provided between the fourth panel 32B and the top wall portion 14. The fourth hinge portion 32C is provided on the outside opposite to the internal space 16. The fifth hinge portion 32D and the sixth hinge portion 32E are provided on the internal space 16 side. The third panel 32A and the fourth panel 32B are rotatably connected by the fourth hinge portion 32C. The second side wall 32 is deformable between an extended first position P1 and an inwardly folded second position P2. The second side wall 32 may further include a second locking mechanism (not shown) that secures the third panel 32A and the fourth panel 32B to prevent the third panel 32A and the fourth panel 32B from moving from the first position P1 to the second position P2.

[0027] 1 and 2, the third panel 32A has a third panel main body 34 and a counter table 35 that can be raised horizontally and folded vertically around an axis provided on the upper part of the third panel main body 34. The fourth panel 32B has a fourth panel main body 36 and a rain cover 37 that can be raised horizontally and folded vertically around an axis provided on the upper part of the fourth panel main body 36.

[0028] The first to sixth hinge parts 32E have the same configuration. Therefore, the following description will focus on the first hinge part 31C. As shown in FIG. 8, each of the first hinge parts 31C includes a first gear 41, a first mounting part 42 attached to the first gear 41, a first shaft part 43 rotatably supporting the first gear 41, a second gear 44 meshing with the first gear 41, a second mounting part 45 attached to the second gear 44, a second shaft part 46 rotatably supporting the second gear 44, and a cover 47 covering the first gear 41 and the second gear 44. The cover 47 is formed to have a C-shaped (box-shaped) cross section, and is provided integrally with the first shaft part 43 and the second shaft part 46. Each member of the first hinge part 31C is made of, for example, an extruded material of an aluminum alloy, and is lightweight. The first mounting part 42 is fixed to the first panel 31A. The second mounting portion 45 is fixed to the second panel 31B. Instead of the aluminum alloy, iron, stainless steel, resin, or the like may be used depending on the application, and by combining these materials, it is possible to take into consideration strength, durability, external environment (changes due to humidity and temperature environment), and safety.

[0029] In the second hinge portion 31D, the first attachment portion 42 is fixed to the bottom portion 12. In the second hinge portion 31D, the second attachment portion 45 is fixed to the first panel 31A. In the third hinge portion 31E, the first attachment portion 42 is fixed to the second panel 31B. In the third hinge portion 31E, the second attachment portion 45 is fixed to the top wall portion 14.

[0030] At the fourth hinge portion 32C, the first mounting portion 42 is fixed to the third panel 32A. At the fourth hinge portion 32C, the second mounting portion 45 is fixed to the fourth panel 32B. At the fifth hinge portion 32D, the first mounting portion 42 is fixed to the bottom portion 12. At the fifth hinge portion 32D, the second mounting portion 45 is fixed to the third panel 32A. At the sixth hinge portion 32E, the first mounting portion 42 is fixed to the fourth panel 32B. At the sixth hinge portion 32E, the second mounting portion 45 is fixed to the top wall portion 14.

[0031] In this way, by configuring each of the first to sixth hinge portions 32E as a geared hinge, the first mounting portion 42 and the second mounting portion 45 are folded (their rotation angles) in a synchronized manner. As a result, when the first side wall portion 31 is folded, the second side wall portion 32 is folded in a synchronized manner, the shape of the side wall portions 15 (first side wall portion 31, second side wall portion 32) of the folding room 11 is stabilized, and the top wall portion 14 is kept approximately horizontal, so that the folding room 11 can be folded and assembled smoothly.

[0032] As shown in FIG. 16, the bottom wall portion 18 is divided into two parts in the short-side direction S of the folding room 11. That is, the bottom wall portion 18 has a first partition wall 18A, a second partition wall 18B, and a pair of seventh hinge portions 18C that rotatably connect either the first partition wall 18A or the second partition wall 18B to the bottom portion 12. Each of the first partition wall 18A and the second partition wall 18B has a length half the length of the floor of the internal space 16 in the folding room 11 in the short-side direction S of the folding room 11. On the other hand, each of the first partition wall 18A and the second partition wall 18B is formed to have the same width as the first panel 31A and the second panel 31B in the longitudinal direction L of the folding room 11. The seventh hinge portion 18C is provided on the internal space 16 side. The seventh hinge portion 18C is a geared hinge, and its configuration is similar to that of the first to sixth hinge portions 31C to 32E.

[0033] 13 to 16, first partition wall 18A and second partition wall 18B are rotatably connected to bottom portion 12 via seventh hinge portion 18C at the end side (first side wall portion 31 side) in the short side direction S of folding room 11. That is, first partition wall 18A and second partition wall 18B of bottom wall portion 18 can rotate between a third position P3 which separates internal space 16 from underfloor space 17 on the bottom portion 12 side as shown in Fig. 16, and a fourth position P4 which stands upright with respect to bottom portion 12 as shown in Fig. 15.

[0034] The actuator unit 21 includes a plurality of actuators that can expand and contract in the axial direction. As shown in Fig. 7 and Fig. 13, the actuator unit 21 includes a pair of first actuators 51 provided corresponding to the first partition wall 18A and a pair of second actuators 52 provided corresponding to the second partition wall 18B. Each of the pair of first actuators 51 is provided so as to extend from an end side (first side wall portion 31 side) of the folding room 11 of the bottom portion 12 in the short side direction S to a center side of the folding room 11 of the first partition wall 18A in the short side direction S. Each of the pair of second actuators 52 is provided so as to extend from an end side (first side wall portion 31 side) of the folding room 11 of the bottom portion 12 in the short side direction S to a center side of the folding room 11 of the second partition wall 18B in the short side direction S.

[0035] Each of the first actuator 51 and the second actuator 52 is configured, for example, by a fluid cylinder. More specifically, each of the first actuator 51 and the second actuator 52 is configured by a pneumatic cylinder. Note that the configuration of the first actuator 51 and the second actuator 52 is not limited to a pneumatic cylinder, and may be a hydraulic cylinder or the like.

[0036] The first actuator 51 and the second actuator 52 can move the first partition 18A and the second partition 18B from the third position P3 to the fourth position P4 by expanding. Also, the first actuator 51 and the second actuator 52 can move the first partition 18A and the second partition 18B from the fourth position P4 to the third position P3 by contracting from a state in which the first partition 18A and the second partition 18B are at the fourth position P4.

[0037] The control panel 22 is preferably attached to a position that is easy for an operator to operate, for example, on the bottom 12, the top wall 14, or the side wall 15. As shown in FIG. 13, the control panel 22 includes a power supply circuit 53 that supplies power to the first actuator 51 and the second actuator 52, a control unit 54 that controls the extension and contraction of the first actuator 51 and the second actuator 52, and an open switch 55 for instructing the extension of the first actuator 51 and the second actuator 52. The control unit 54 is composed of, for example, a one-chip microcomputer, a driver that directly controls the first actuator 51 and the second actuator 52, and a control circuit in which these are implemented. Software that controls the first actuator 51 and the second actuator 52 to be synchronously extended or contracted is installed in the one-chip microcomputer.

[0038] Next, the folding and assembling operations of the folding loom 11 of this embodiment will be described with reference to Figures 11 to 16 etc. As shown in Figure 1, when the folding loom 11 is in an assembled state, the first side wall portion 31 and the second side wall portion 32 are both in an extended first position P1.

[0039] 11, the sealing wall 24 is moved from the upright position S1 to a horizontally-tilted position S2 in which it is tilted sideways against the bottom 12 toward the interior space 16 via the hinge. Similarly, the door 23 is moved from the upright position S1 to a horizontally-tilted position S2 in which it is tilted sideways against the bottom 12 toward the interior space 16 via the hinge, whereby the door 23 is placed on the upper side of the sealing wall 24.

[0040] Next, in the case where a first locking mechanism and a second locking mechanism are provided, the first locking mechanism and the second locking mechanism are released prior to the folding operation of the folding room 11. This makes it possible for the first side wall portion 31 and the second side wall portion 32 to be folded.

[0041] In this state, the worker pushes the first side wall portion 31 and the second side wall portion 32 of the side wall portion 15 inward (toward the internal space 16), so that the first side wall portion 31 and the second side wall portion 32 gradually move from the extended first position P1 to the inwardly folded second position P2. At that time, the worker may fold the folding room 11 while appropriately supporting a part of the top wall portion 14 with his / her hand.

[0042] At this time, due to the action of the first to sixth hinge portions 32E with gears, folding is performed synchronously between the first side wall portion 31 and the second side wall portion 32. Therefore, a problem does not occur in which the degree of folding of the second side wall portion 32 is smaller than the degree of folding of the first side wall portion 31.

[0043] In the first side wall portion 31, the inclination (rotation angle) of the first panel 31A and the second panel 31B with respect to the horizontal plane becomes uniform due to the action of the first to third hinge portions 31E with gears. Similarly, in the second side wall portion 32, the inclination (rotation angle) of the third panel 32A and the fourth panel 32B with respect to the horizontal plane becomes uniform due to the action of the fourth to sixth hinge portions 32E with gears.

[0044] As a result, the top wall 14 is maintained in a substantially horizontal state while the first side wall 31 and the second side wall 32 are being folded from the first position P1 to the second position P2. Therefore, the overall shape of the folding room 11 does not become unstable during the folding operation.

[0045] When the folding loom 11 is completely folded, the folding loom 11 becomes flat and space-saving. In this state, the folding looms 11 can be stored, for example, by stacking two or three of them. Alternatively, the folding looms 11 can be lifted by, for example, a crane and loaded onto the bed of a vehicle. As shown in FIG. 12, the folding looms 11 can also be loaded, for example, by stacking two or three of them on the bed of a vehicle. Note that FIG. 12 shows the folding loom 11 without the legs 13, and the height of two or three folding looms 11 having the legs 13 stacked on top of each other is slightly higher than that shown in the figure, but is still high enough to be installed on the bed of a vehicle.

[0046] On the other hand, the actuator unit 21 can be used to assemble the folding loom 11 in the folded state so that it can be used. First, the folding loom 11 is placed on a substantially horizontal, flat floor or the like. As shown in Fig. 13, when an operator operates the open switch 55 of the control panel 22 in this state, the control unit 54 of the control panel 22 controls the power supply circuit 53 to supply power to the first actuator 51 and the second actuator 52, causing the first actuator 51 and the second actuator 52 to extend in a synchronized manner.

[0047] When the first actuator 51 and the second actuator 52 extend in a synchronous manner, the first partition 18A and the second partition 18B of the bottom wall portion 18 rotate in a synchronous manner around the seventh hinge portion 18C. As a result, as shown in FIG. 14, the first partition 18A and the second partition 18B move from the third position P3 in a laid-down state to the fourth position P4 in an upright state. At that time, the first partition 18A and the second partition 18B can lift up the first side wall portion 31 located at the second position P2 together. That is, the first partition 18A and the second partition 18B move from the third position P3 to the fourth position P4 by the driving force of the first actuator 51 and the second actuator 52, thereby moving the first side wall portion 31 from the second position P2 to the first position P1 shown in FIG. 15. At that time, the second side wall portion 32 moves from the second position P2 to the first position P1 in synchronization with the first side wall portion 31. Therefore, when the side wall portion 15 (the first side wall portion 31 and the second side wall portion 32) moves from the second position P2 to the first position P1, the top wall portion 14 can maintain a substantially horizontal state. Note that, in this embodiment, the actuator unit 21 moves the first side wall portion 31 from the second position P2 to the first position P1, but this is not limited thereto, and a structure in which the actuator unit 21 moves the second side wall portion 33 from the second position P2 to the first position P1 may be adopted.

[0048] Further, as shown in FIG. 15 and FIG. 16, the first actuator 51 and the second actuator 52 are shortened to their original length by the control of the control unit 54, and the first partition wall 18A and the second partition wall 18B of the bottom wall portion 18 move from the fourth position P4 to the third position P3. Meanwhile, the side wall portion 15 (the first side wall portion 31 and the second side wall portion 32) maintains the state of the second position P2. In this state, the worker fixes the first lock mechanism and the second lock mechanism to prevent the first side wall portion 31 and the second side wall portion 32 from returning from the first position P1 to the second position P2. In this state, the folding room 11 is in the state shown in FIG. 11. In this state, the bottom wall portion 18 becomes approximately horizontal, and the user can use the indoor space.

[0049] The worker rotates the pair of doors 23 from the horizontally laid position S2 to the standing position S1, and fixes the pair of doors 23 to the first panel 31A and the second panel 31B. The worker then rotates the pair of sealing walls 24 from the horizontally laid position S2 to the standing position S1, and fixes the pair of sealing walls 24 to the first panel 31A and the second panel 31B. This places the folding room 11 in the state shown in FIG. 1, and the assembly is completed.

[0050] According to this embodiment, the following can be said: The folding room 11 includes a bottom 12, a top wall 14 facing the bottom 12, a side wall 15 connecting the bottom 12 and the top wall 14 and deformable between a first position P1 in which the bottom 12 is extended and a second position P2 in which the bottom 12 is folded inward, a bottom wall 18 provided rotatably with respect to the bottom 12, the bottom wall 18 being rotatable between a third position P3 that separates an internal space 16 surrounded by the top wall 14 and the side wall 15 from an underfloor space 17 on the bottom 12 side, and a fourth position P4 that stands up relative to the bottom 12 and can lift the side wall 15 at the second position P2 to the first position P1, and an actuator that is stored in the underfloor space 17 and fixed to the bottom 12, and that rotates the bottom wall 18 between the first position P1 and the second position P2.

[0051] According to this configuration, the actuator can automatically fold and assemble the folding room 11. In addition, because the actuator is stored in the underfloor space 17, the actuator is not exposed in the internal space 16. This eliminates the risk of a user tripping over the actuator, and makes it possible to realize a folding room 11 that is easy to use.

[0052] The actuator is composed of various known cylinders such as electric or hydraulic cylinders that can be extended and retracted. With this configuration, the structure of the actuator can be simplified and the folding room 11 can be assembled in a short time. Also, the actuator can be realized as a space-saving one, and for example, the actuator can be stored in the underfloor space 17.

[0053] In the following embodiment, differences from the above embodiment will be mainly described, and illustrations or descriptions of parts common to the above embodiment will be omitted. [Second embodiment]

[0054] The folding room 11 of the second embodiment will be described with reference to Fig. 17. Note that in Fig. 17, illustration of the legs 13 other than the base 13A is omitted.

[0055] In this embodiment, an operator can manually assemble the folding loom 11 from the folded state.

[0056] In addition to the actuator unit 21, the folding room 11 further includes an elevator unit 61 capable of manually lifting the top wall portion 14. This elevator unit 61 allows the top wall portion 14 to be lifted manually to assemble the folding room 11 when power is lost in an emergency such as an earthquake. The elevator unit 61 is an example of the lift mechanism referred to in the present invention.

[0057] The bottom 12 of the folding room 11 has a recess 62 for storing the elevator unit 61. In this embodiment, the actuator unit 21 and the bottom wall portion 18 (first partition wall 18A, second partition wall 18B) are provided at a position outside the recess 62, but have the same configuration as in the first embodiment.

[0058] The elevator unit 61 has a lift plate 63 capable of supporting the top wall 14 by contacting the bottom surface of the top wall 14, a bellows-shaped telescopic part 64 for lifting and lowering the lift plate 63, a rail 65 for guiding the lower end of the telescopic part 64 so that it can slide, a rack 66 formed adjacent to the rail 65, a pinion 67 rotatably provided at the lower end of the telescopic part 64 and engaging with the rack 66, and a handle 68 for rotating the pinion 67. The handle 68 is fixed, for example, by welding or brazing so as to be integral with the pinion 67. The telescopic part 64 can lift and lower the top wall 14 via the lift plate 63. The handle 68 can be manually rotated by an operator to extend or shorten the telescopic part 64.

[0059] Next, the assembly and folding operations of the folding loom 11 of this embodiment will be described with reference to FIG.

[0060] When the folding room 11 is in the folded state, the lift plate 63 is housed in the recess 62. In this state, the lift plate 63 and the surrounding bottom wall portion 18 (first partition wall 18A, second partition wall 18B) are flush with each other.

[0061] When the operator rotates the handle 68 in the direction of the arrow, the pinion 67 rotates and travels on the rack 66. This causes the lower end of the extension part 64 to move, and the extension part 64 extends in the height direction. This allows the lifting plate 63 to lift the top wall part 14.

[0062] Accordingly, the first side wall portion 31 and the second side wall portion 32 move from the second position P2 to the first position P1. In this state, the worker activates the first locking mechanism and the second locking mechanism to prevent the first side wall portion 31 and the second side wall portion 32 from returning to the second position P2 again.

[0063] Then, the worker rotates the handle 68 in the direction opposite to the direction indicated by the arrow, so that the pinion 67 rotates and travels on the rack 66. As a result, the lower end of the extension / contraction portion 64 moves in the direction opposite to the above-mentioned moving direction, and the extension / contraction portion 64 shortens in the height direction. When the shortening of the extension / contraction portion 64 is completed, the lift plate 63 is stored in the recess 62. In this state, the lift plate 63 in the recess 62 is flush with the surrounding bottom wall portion 18 (the first partition wall 18A and the second partition wall 18B), and the user can use the internal space 16 inside the folding room 11. The worker moves the door 23 from the horizontally laid position S2 to the standing position S1 and fixes the door 23 to the first panel 31A and the second panel 31B. Similarly, the worker moves the sealing wall 24 from the horizontally laid position S2 to the standing position S1 and fixes the sealing wall 24 to the first panel 31A and the second panel 31B. This completes the assembly of the folding loom 11.

[0064] On the other hand, when folding the folding loom 11, it can be folded in the same manner as in the first embodiment.

[0065] According to this embodiment, the following can be said: The folding room 11 is provided with a lift mechanism that expands and contracts by manual operation to lift the top wall portion 14 upward and move the side wall portion 15 from the second position P2 to the first position P1.

[0066] The folding room 11 also includes a bottom 12, a top wall 14 facing the bottom 12, a side wall 15 connecting the bottom 12 and the top wall 14 and deformable between an extended first position P1 and a folded-inward second position P2, a bellows-shaped extension / contraction portion 64 for raising and lowering the top wall 14, and a handle 68 for extending or shortening the extension / contraction portion 64.

[0067] According to these configurations, even in a situation where electricity is unavailable due to a natural disaster such as an earthquake, the folding loom 11 can be assembled by manually rotating the handle 68. [Third embodiment]

[0068] With reference to FIG. 18, a folding room 11 according to a third embodiment will be described.

[0069] In addition to the actuator unit 21, the folding room 11 further has a hand lifter 71 capable of manually lifting the top wall portion 14. This hand lifter 71 allows the top wall portion 14 to be lifted manually to assemble the folding room 11 when power is lost in an emergency such as an earthquake. The hand lifter 71 is an example of a lift mechanism referred to in the present invention.

[0070] The hand lifter 71 has a base part 72 that can be inserted under the bottom part 12, a support part 73 that stands from the base part 72, a lifting handle 74 provided in the middle of the support part 73, a pulley 75 provided at the top of the support part 73, a chain (not shown) wound around the pulley 75, a fork part 76 that rises and falls with the rotation of the lifting handle 74, and caster parts 77 provided on the base part 72 and the support part 73. In this hand lifter 71, when an operator rotates the lifting handle 74 in one direction, the chain is wound and pulled, and the fork part 76 can be lifted up to a height near the pulley 75 via the chain. When an operator rotates in the opposite direction to the one direction, the chain is unwound and loosened, and the fork part 76 can be lowered via the chain in a direction away from the pulley 75. A commercially available hand lifter 71 can also be used.

[0071] Next, an operation for assembling the folding room 11 of this embodiment will be described. As shown in Fig. 18, the worker inserts the fork portion 76 of the hand lifter 71 into at least one of the opening 33 corresponding to the door 23 and the opening 33 corresponding to the sealing wall 24. At this time, the base portion 72 is placed below the bottom portion 12. Note that the hand lifter 71 may be one unit, or two units may be arranged diagonally to lift the top wall portion 14 from both sides.

[0072] When the operator rotates the lift handle 74 in one direction to raise the fork portion 76, the fork portion 76 comes into contact with the underside of the top wall portion 14 and lifts the top wall portion 14 upward. This causes the side wall portion 15 (first side wall portion 31, second side wall portion 32) to move from the second position P2 to the first position P1. In this state, the operator activates the first locking mechanism and the second locking mechanism to prevent the first side wall portion 31 and the second side wall portion 32 from returning to the second position P2 again.

[0073] The worker moves the door 23 from the horizontally laid position S2 to the standing position S1 and fixes the door 23 to the first panel 31A and the second panel 31B. Similarly, the worker moves the sealing wall 24 from the horizontally laid position S2 to the standing position S1 and fixes the sealing wall 24 to the first panel 31A and the second panel 31B. This completes the assembly of the folding room 11.

[0074] On the other hand, when folding the folding loom 11, it can be folded in the same manner as in the first embodiment.

[0075] According to this embodiment, the following can be said: The folding room 11 includes a bottom 12, a top wall 14 facing the bottom 12, a side wall 15 connecting the bottom 12 and the top wall 14 and deformable between a first extended position P1 and a second folded-inward position P2, and a hand lifter 71 capable of lifting the top wall 14, and the hand lifter 71 has a base portion 72, a support portion 73 standing from the base portion 72, a lifting handle 74 provided on the support portion 73, and a fork portion 76 that can be inserted under the top wall 14 and rises and falls as the lifting handle 74 rotates.

[0076] According to this configuration, even in a situation where electricity is unavailable due to a natural disaster such as an earthquake, the folding room 11 can be assembled by manually rotating the lifting handle 74.

[0077] Next, a modified example of the folding room 11 of this embodiment will be described with reference to FIG.

[0078] In this modification, the bottom 12 of the folding room 11 is provided with an attachment part 81 having an insertion hole 81A (recess) as shown in Fig. 19. The base part 72 of the hand lifter 71 does not have caster parts 77, but instead has a shaft part 82 that can be inserted into the insertion hole 81A of the attachment part 81. Therefore, in this modification, the hand lifter 71 can be fixed to the bottom 12. According to this modification, when an operator operates the lifting handle 74, the hand lifter 71 does not wobble, and the work of assembling the folding room 11 can be performed smoothly.

[0079] With reference to FIG. 19, the assembly and folding operations of the folding loom 11 of this embodiment will be described.

[0080] In this modified example, prior to assembling the folding room 11, the fork portion 76 of the hand lifter 71 is inserted into the opening 33 corresponding to the door 23 or the opening 33 corresponding to the sealing wall 24, while the shaft portion 82 of the hand lifter 71 is inserted into the insertion hole 81A of the mounting portion 81. In this state, the worker rotates the lifting handle 74 in one direction. This moves the top wall portion 14 from the second position P2 to the first position P1. The subsequent assembly and folding operations are the same as those of the pre-modified form described above.

[0081] According to this modification, the following can be said: The bottom portion 12 has an attachment portion 81 to which the lift mechanism can be detachably attached. The bottom portion 12 has an attachment portion 81 including an insertion hole 81A, and the base portion 72 has a shaft portion 82 that can be inserted into the insertion hole 81A.

[0082] According to this configuration, when the lift mechanism is operated manually, the position of the lift mechanism is stabilized by the mounting portion 81. As a result, the lift mechanism does not wobble when assembling the folding loom 11, and work efficiency can be improved. [Fourth embodiment]

[0083] The folding room 11 of the fourth embodiment will be described with reference to FIGS.

[0084] In addition to the actuator unit 21, the folding room 11 further includes a temporary crane 91 capable of manually lifting the top wall portion 14. This temporary crane 91 allows the top wall portion 14 to be lifted manually to assemble the folding room 11 when power is lost in an emergency such as an earthquake. The temporary crane 91 is an example of a lift mechanism as referred to in the present invention.

[0085] The temporary crane 91 has a tower 92 installed above the folding room 11 (top wall portion 14), a manual hoist 93 (chain block) attached to the tower 92, and a caster portion 77 that movably supports the tower 92. In Fig. 20, the chain for manually operating the hoist 93 is not shown. A commercially available temporary crane 91 can also be used.

[0086] As shown in FIG. 21, the top wall portion 14 of the folding room 11 has a hook portion 94 for hooking a hook 93A of a hoist 93 thereon.

[0087] Next, an assembly operation of the folding room 11 of this embodiment will be described. As shown in Fig. 21, an operator hangs the hook 93A of the hoist 93 on the hanging part 94. Note that Fig. 21 corresponds to a modified example provided with the mounting part 81, which will be described later, but the caster part 77 may be provided.

[0088] When the worker pulls the chain of the hoist 93 to raise the hook 93A, the top wall 14 can be lifted upward. This causes the side wall 15 (first side wall 31, second side wall 32) to move from the second position P2 to the first position P1. In this state, the worker activates the first locking mechanism and the second locking mechanism to prevent the first side wall 31 and the second side wall 32 from returning to the second position P2 again.

[0089] The worker moves the door 23 from the horizontally laid position S2 to the standing position S1, and fixes the door 23 to the first panel 31A and the second panel 31B. Similarly, the worker moves the sealing wall 24 from the horizontally laid position S2 to the standing position S1, and fixes the sealing wall 24 to the first panel 31A and the second panel 31B. Furthermore, the worker removes the hook 93A of the hoist 93 from the hanging portion 94. This completes the assembly of the folding room 11.

[0090] On the other hand, when folding the folding loom 11, it can be folded in the same manner as in the first embodiment.

[0091] According to this embodiment, the following can be said: The folding room 11 includes a bottom 12, a top wall 14 facing the bottom 12, a side wall 15 connecting the bottom 12 and the top wall 14 and deformable between a first extended position P1 and a second folded-inward position P2, a tower 92 installed above the top wall 14, and a manual hoist 93 attached to the tower 92 and capable of lifting the top wall 14.

[0092] According to this configuration, even in a situation where power is unavailable due to a natural disaster such as an earthquake, the folding room 11 can be assembled by manually operating the manual hoist 93.

[0093] In this embodiment, as in the modified example of the third embodiment, a mounting part 81 having an insertion hole 81A may be provided on the bottom 12 of the folding room 11, and a shaft part 82 that can be inserted into the insertion hole 81A of the mounting part 81 may be provided on the lower end of the tower 92 instead of the caster part 77 (see FIG. 21). In this modified example, a temporary crane 91 can be attached to the bottom 12, and the temporary crane 91 does not wobble when the hoist 93 is operated, allowing the folding room 11 to be smoothly assembled.

[0094] According to this modified example, the following can be said: The bottom portion 12 has an attachment portion 81 including an insertion hole 81A, and the tower has a shaft portion 82 that can be inserted into the insertion hole 81A.

[0095] According to this configuration, when the lift mechanism is operated manually, the position of the lift mechanism is stabilized by the mounting portion 81. This makes it possible to improve the work efficiency when assembling the folding loom 11. [Fifth embodiment]

[0096] The folding room 11 of the present invention may be configured without the actuator unit 21 of the first embodiment. That is, the folding room 11 has a bottom 12, a top wall 14 facing the bottom 12, and a side wall 15 connecting the bottom 12 and the top wall 14 and deformable between an extended first position P1 and an inwardly folded second position P2, and the connecting parts of these members are connected by a geared hinge, thereby achieving a reduction in the weight of the bottom 12.

[0097] The above-described embodiments can be implemented with various further substitutions and modifications. Naturally, the invention can also be appropriately configured by combining the configurations of the respective embodiments and modifications. In the above-described first to fifth embodiments, the first to seventh hinge portions 31C to 18C, which are configured as hinges with gears, can also be changed to normal hinges (hinges without gears).
