Description

[Technical Field]

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

[0002] Conventionally, booths with ceilings have been known, such as those shown in Patent Documents 1 and 2, in which a heat-reactive fire extinguisher is installed above the ceiling, allowing for rapid extinguishing of a fire even if it occurs within the interior space of the booth. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-204231 [Patent Document 2] Patent Publication No. 2021-070973 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in conventional booths, fire extinguishers had to be installed from above the ceiling. This made installation difficult when the booth's upper height was not sufficient, such as when the booth was installed inside a building. Furthermore, fire extinguishers required regular inspection and replacement, which required workers to set up a stepladder outside the booth and reach the ceiling. This stepladder was a hindrance during work, and the heavy fire extinguisher had to be lifted and lowered above the ceiling, leaving room for improvement in terms of workability.

[0005] In addition, in the case of Patent Document 2, after the fire extinguisher was installed in a designated position on the ceiling, the interior panel that constitutes the ceiling surface of the booth was installed, so at least the fire extinguisher installation process and the inner panel installation process had to be carried out.

[0006] Therefore, the present invention has been made in consideration of the above circumstances, and provides a booth in which a fire extinguisher can be easily attached to the ceiling surface from inside the booth. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention employs the following means. In other words, the booth of the present invention comprises a booth body having an opening in the ceiling surface and forming an internal space, and a fire extinguisher unit provided above the ceiling surface so as to cover at least a portion of the opening, the fire extinguisher unit comprising a fire extinguisher that contains a fire extinguishing agent and sprays the fire extinguishing agent downward when a fire is detected, and a locking portion that locks from above to both sides of the ceiling surface that sandwich the opening in a direction intersecting the vertical direction, and the fire extinguisher is provided so as to be able to pass through the opening.

[0008] In the booth of the present invention, a fire extinguisher can be installed above the ceiling from inside the booth (inner space side) through an opening in the ceiling, which has the advantage of eliminating the cumbersome task of installing a fire extinguisher from outside the booth as in the past. In this case, the opening can be blocked by part of the underside of the fire extinguisher unit after installation on the ceiling surface. In this way, the booth according to the present invention allows the fire extinguisher to be installed on the ceiling surface efficiently. Furthermore, in the present invention, the opening formed in the ceiling surface only needs to be large enough to allow the fire extinguisher to be inserted from the interior space side to the upper side of the ceiling surface, and does not need to be the size or shape of the fire extinguisher when viewed from above in a plan view when installed, so the opening can be made small. In other words, since it is possible to increase the degree of freedom in the opening, it is possible to reduce space restrictions caused by the opening, and other booth equipment to be installed in the ceiling surface can be efficiently arranged.

[0009] In the booth according to the present invention, the fire extinguisher unit may be arranged so as to be able to pass through the opening.

[0010] In a booth configured in this manner, the opening can be blocked by part of the underside of the fire extinguisher unit after it is installed on the ceiling surface simply by attaching the fire extinguisher unit to the ceiling surface, eliminating the need for the work of blocking the opening after installation.

[0011] In addition, in the booth of the present invention, the fire extinguisher unit may be characterized in that it has a blocking plate that is engaged with at least a portion of the underside of the fire extinguisher, is provided separately from the fire extinguisher, and is formed to the same size as the opening, and the blocking plate is positioned in a state that blocks the opening when the engaging portion engages with the upper side of the ceiling surface.

[0012] In a booth configured in this way, a separate cover plate that covers the opening can be attached to the underside of the fire extinguisher unit, so that a cover plate shaped to fit the ceiling surface around the opening can be provided. Therefore, even if the underside of the fire extinguisher does not match the shape of the opening, by attaching the cover plate to the underside of the fire extinguisher, the opening can be easily installed flat along the ceiling surface. In this case, by using the same material and color for the closing plate as the ceiling surface, the appearance of the portion exposed in the opening and the ceiling surface is not marred, and the design can be improved.

[0013] In addition, in the booth of the present invention, when viewed in a plane, the blocking plate has two opposing parallel sides and a connecting side connecting the ends of the two opposing sides, the locking portion is provided on the outer portion of the connecting side of the blocking plate, and one of the pair of locking portions is provided with an abutment member that positions the fire extinguisher in a direction along the surface of the ceiling surface, and the blocking plate may be characterized in that when the abutment member abuts a positioning portion provided on the upper surface of the ceiling surface, the blocking plate overlaps the opening in the vertical direction.

[0014] In a booth configured in this manner, when the fire extinguisher unit is inserted into the upper part of the ceiling surface through the opening and the locking portion is locked onto the upper surface of the ceiling surface, the fire extinguisher unit can be easily positioned and installed by moving the fire extinguisher unit in the direction of the surface of the ceiling surface and abutting the abutment member provided on one of the locking portions against the positioning portion on the ceiling surface.

[0015] In addition, in the booth of the present invention, the ceiling surface may be formed with a downward recess that is concave downward, and have a fire extinguisher cover that houses the fire extinguisher unit, and the opening may be provided in the fire extinguisher cover.

[0016] In a booth configured in this manner, a portion of the lower part of the fire extinguisher unit is housed in a downward recess that is lower than the ceiling surface, thereby reducing the height of the fire extinguisher unit above the ceiling surface. This allows the distance between the ceiling surface and the upper wall of the booth to be reduced, and the height of the booth itself to be kept low. In addition, in the present invention, the downward recess in the ceiling surface functions as a housing for the fire extinguisher unit and also as a cover that covers the fire extinguisher unit. In addition, in the present invention, when installing the fire extinguisher unit, the fire extinguisher unit is installed at the opening of the fire extinguisher cover, which is located below the ceiling surface, so work can be performed at a lower position, improving workability.

[0017] In addition, in the booth according to the present invention, the fire extinguisher cover may be provided with lighting that illuminates the internal space.

[0018] In a booth configured in this manner, even if a fire extinguisher cover is installed that is recessed below the ceiling surface, lighting is provided on the underside of the fire extinguisher cover, so the light emitted from the lighting is not blocked by the fire extinguisher cover, making it possible to provide a booth that is easy to use. [Effects of the Invention]

[0019] According to the booth of the present invention, a fire extinguisher can be easily attached to the ceiling surface from inside the booth. [Brief explanation of the drawings]

[0021] Hereinafter, a booth according to one embodiment of the present invention will be described with reference to FIGS.

[0022] The booth 1 of this embodiment is installed on the floor of an office, public institution, etc., and forms an internal space K1 where work is carried out, isolated from the external space. The booth 1 of this embodiment is equipped with a sliding door 4 made of a hanging door that opens and closes an entrance opening E that separates the internal space K1 from the external space K2.

[0023] 1 to 4, in the following description, the side from which a user working in the internal space K1 of the booth 1 enters and exits between the external space K2 and the internal space K1 is referred to as the "front," the right-hand side of a user facing the booth 1 from the front is referred to as the "right," the left-hand side is referred to as the "left," and the upper side of the booth 1 as seen from a user facing the booth 1 from the front is referred to as the "rear." In other words, the direction of entering and exiting the external space K2 and the internal space K1 is referred to as the front-rear direction X1, and the direction perpendicular to the front-rear direction X1 as seen from above is referred to as the left-right direction X2 or width direction X2.

[0024] As shown in FIG. 1, the booth 1 according to this embodiment includes a floor 2, an outer wall 3 (booth body), a sliding door 4, and an upper guide mechanism 5.

[0025] The floor section 2 is placed directly on the floor surface F on which the booth 1 of this embodiment is to be installed, and supports the outer wall section 3 from below. The underside of the floor section 2 is provided with a plurality of casters and a plurality of height-adjustable adjusters at appropriate positions. The casters are arranged so that they can come into contact with the floor surface F, and by rolling, the entire booth 1 can be easily moved. Furthermore, when installing the booth 1, by contacting the adjusters with the floor surface F, the casters are separated from the floor surface F, restricting movement of the booth 1.

[0026] A part of the front end of the floor 2 has an entrance / exit section 23 of the booth 1 below the entrance / exit opening E. The entrance / exit section 23 has an arc shape that follows the shape of the door surface of the sliding door 4, and forms a convex curved surface that is convex outward.

[0027] As shown in FIG. 1 , the outer wall portion 3 includes support columns 31, side walls 32, and a ceiling wall 33. The support columns 31 are column members erected on the floor portion 2. The support columns 31 are arranged at each of the four corners of the rectangular floor portion 2 in a plan view. These four support columns 31 have the same height. However, the height dimensions of these support columns 31 may differ. The number of support columns 31 can also be changed. The side walls 32 are arranged between each of the support columns 31. The side walls 32 include a front wall portion 32A arranged in front of the booth 1, a right wall portion 32B arranged on the right side of the booth 1, a left wall portion 32C arranged on the left side of the booth 1, and a rear wall portion 32D arranged on the rear side of the booth 1.

[0028] Between a pair of support pillars 31, 31 provided on the front side of the outer wall 3 are a front wall 32A fixed to the left support pillar 31, and an entrance / exit opening E forming an entrance / exit for users, with a sliding door 4 arranged between the front wall 32A and the right support pillar 31 so that it can be opened and closed. The front wall 32A is erected on the floor surface of the floor 2, and the lower part of the front wall 32A and the lower part of the right support pillar 31 are connected by the entrance / exit part 23 of the floor 2.

[0029] As shown in FIG. 1 , a desk 70 consisting of a tabletop is provided at the rear side of the interior space K1 surrounded by the front wall 32A, right wall 32B, left wall 32C, and rear wall 32D. In other words, the desk 70 is positioned opposite the entrance opening E with a chair (not shown) in between. The desk 70 is attached to the inner wall surface 32a of the rear wall 32D and extends forward from the rear wall 32D. The right edge of the desk 70 is fixed to the right wall 32B, and the left edge is fixed to the left wall 32C. The height of the desk 70 is set to a height that can be used by a user seated in a chair (not shown).

[0030] The ceiling wall 33 is supported from below by the support columns 31 and the side walls 32, thereby closing off the interior space K1 from above. This ceiling wall 33 includes a ceiling frame (not shown) and a ceiling panel 33A. The ceiling frame is a frame-shaped member that surrounds the ceiling panel 33A horizontally and is connected to the periphery of the ceiling panel 33A, and is fixed to the upper ends of the support columns 31 and the side walls 32. The ceiling panel 33A is a plate-shaped member that is supported by the ceiling frame and is arranged inside the ceiling frame in a plan view.

[0031] In this embodiment, an equipment housing section 76 for housing part of the booth equipment 7 is provided above the ceiling panel 33A.

[0032] As shown in FIG. 1, the sliding door 4 is a hanging door suspended and supported by an upper guide mechanism 5 so as to be able to open and close. The sliding door 4 is a door body curved in an arc about a pivot axis C (see FIG. 3), and is capable of opening and closing the entrance opening E by the upper guide mechanism 5. The sliding door 4 includes a glass panel 41, and an upper edge frame 42, a lower edge frame 43, and side edge frames 44 made of, for example, an aluminum alloy. The sliding door 4 pivots about the pivot axis C and enters the interior space K1 in an open state.

[0033] The glass panel 41 is a panel body made of glass and has a rectangular shape when viewed from the front-rear direction X1. Note that the glass panel 41 is used to ensure the light transmittance of the sliding door 4, but if light transmittance is not required, a panel body made of another material can also be used.

[0034] The sliding door 4 has a curved shape such that the center portion bulges toward the external space K2 in a plan view. When the sliding door 4 is placed in a closed position, which is a position for closing the entrance / exit opening E, the center portion of this sliding door 4 protrudes toward the external space K2 beyond the outer wall surface of the front wall 32A in a plan view. In other words, as shown in FIG. 2, when the sliding door 4 is closed, the center portion of the sliding door 4 protrudes forward beyond the outer wall surface of the front wall 32A. Such a sliding door 4 is capable of pivoting about a pivot axis C aligned in the vertical direction to open and close the entrance / exit opening E.

[0035] As shown in FIG. 1, the upper guide mechanism 5 is suspended and supported on the front side of the ceiling wall 33, and is disposed above the entrance opening E provided in the front wall portion 32A.

[0036] The upper guide mechanism 5 is provided on the ceiling surface 33a and includes a guide rail 51 that suspends and supports the sliding door 4 so that the sliding door 4 can be opened and closed in a circumferential direction around a rotation axis C shown in FIG. 3 along the vertical direction. In other words, the upper edge frame 42 of the sliding door 4 is supported by the upper guide mechanism 5. For example, the upper guide mechanism 5 includes a linear motor (not shown). When the upper guide mechanism 5 includes a linear motor in this way, the sliding door 4 moves automatically.

[0037] Next, the booth equipment provided on the ceiling surface 33a of the ceiling wall 33 will be specifically described.

[0038] As shown in FIGS. 2 and 3, the ceiling surface 33a of the ceiling wall 33 is provided with the guide rails 51 of the upper guide mechanism 5, the fire extinguisher unit 60, the ventilation holes 72, the speakers 73, and the lights 74. A portion of the guide rail 51 located in the internal space K1 is disposed on one side (left side) of the ceiling surface 33a in the width direction X2. The fire extinguisher unit 60 is disposed in the center of the ceiling surface 33a, in the center in the width direction X2.

[0039] The ventilation opening 72 is an opening that connects the internal space K1 and the external space K2, and is disposed in the first space S1 of the ceiling surface 33a on the opposite side of the guide rail 51 across the fire extinguisher unit 60 in the width direction X2.

[0040] The speaker 73 is disposed in a second space S2 between the fire extinguisher unit 60 and the guide rail 51. The second space S2 is a restricted area that is on the inside of a circular arc that bulges outward in the width direction of the guide rail 51. The speaker 73 is provided in an opening that is circular in plan view and formed in the ceiling surface 33a.

[0041] The lighting 74 is disposed in the third space S3 of the ceiling surface 33a on the opposite side of the entrance opening E between the internal space K1 and the external space K2, across the fire extinguisher unit 60 in the front-rear direction X1.

[0042] Here, ceiling surface 33a is formed with downward recess 33c that is recessed downward, and has fire extinguisher cover 33B that houses fire extinguisher unit 60. As shown in Figures 4 and 5, lower surface 33d of fire extinguisher cover 33B is provided with opening 33C in which fire extinguisher unit 60 is installed. Fire extinguisher unit 60 is provided so as to be able to pass through opening 33C.

[0043] As shown in FIG. 5, the above-mentioned light 74 for illuminating the internal space K1 is provided on the underside 33d of the fire extinguisher cover 33B.

[0044] 4 and 5, fire extinguisher unit 60 is provided above ceiling surface 33a so as to cover opening 33C. Fire extinguisher unit 60 includes fire extinguisher 61 that stores a fire extinguishing agent and sprays the fire extinguishing agent downward when a fire is detected, and locking portions 62 that are provided on both the front and rear sides of ceiling surface 33a across opening 33C in a direction intersecting the up-down direction and that lock onto the upper side of ceiling surface 33a with at least a portion of the underside of fire extinguisher 61 covering opening 33C.

[0045] Furthermore, the fire extinguisher unit 60 is provided separately from the fire extinguisher 61 and is engaged with at least a portion of the underside 61a of the fire extinguisher 61, and has a blocking plate 63 that is rectangular in plan view and is formed to the same size as the opening 33C. When the locking portion 62 is locked to the upper side of the ceiling surface 33a, the closing plate 63 is disposed in a state where it closes the opening 33C.

[0046] As shown in Figures 6 to 8, the locking portions 62 are provided on the outer portions of two sides of the closing plate 63 that face each other in the front-rear direction X1. One of the pair of locking portions 62 is provided with a locking plate 65 having an L-shaped cross section. The locking plate 65 has substantially the same shape as one of the locking portions 62 in a plan view seen from the top-bottom direction. The locking plate 65 has a locking surface 65A that overlaps one of the locking portions 62, and an abutment member 65B that protrudes downward from the outer edge of the locking surface 65A. The locking surface 65A is fixed to one of the locking portions 62 with a fixing member such as a screw.

[0047] As shown in Fig. 4, the abutment member 65B has the function of positioning the fire extinguisher 61 in a direction along the surface of the ceiling surface 33a. When the abutment member 65B abuts against a support beam 36 (positioning portion) provided on the upper surface of the ceiling surface 33a, the closing plate 63 overlaps the opening 33C in the vertical direction. The support beam 36 is a beam member that is arranged to extend in the front-rear direction X1 on both sides of the opening 33C in the width direction X2 (see Fig. 11(a)).

[0048] As shown in Figures 9 and 10, the fire extinguisher 61 is rectangular in plan view. The underside 61a of the fire extinguisher 61 has a rectangular frame portion 64 in the center in one direction (here, the left-right direction X2) that has approximately the same shape as the opening 33C in plan view. The aforementioned locking portions 62 are provided on both the front and rear ends of the rectangular frame portion 64. The rectangular frame portion 64 protrudes downward from the underside 61a of the fire extinguisher 61. The centers of a pair of horizontal frame members 64A extending in the left-right direction X2 are open. A closing plate 63 is engaged with the rectangular frame portion 64 by, for example, adhesive means.

[0049] The distance L3 between the opposing connecting edges 63b of the closing plate 63 on the side where the locking portion 62 is arranged is set to be longer than the distance L1 from the closing plate 63 to the upper end 61b of the fire extinguisher 61, and shorter than the length L2 of the opposing edges 61c on the side where the locking portion 62 is arranged of the fire extinguisher 61. The distance L4 between the other opposing edges 61c of the closing plate 63 is set to be equal to the maximum length L2 of the other opposing edge 61d of the fire extinguisher 61.

[0050] As shown in Figure 4, the vertical length L5 from the lower surface 33d of the fire extinguisher cover 33B to the ceiling surface 33a is set to be smaller than the height dimension L1 (see Figure 9) from the blocking plate 63 to the upper end 61b of the fire extinguisher 61.

[0051] When the fire extinguisher unit 60 is attached to the ceiling surface 33a, it is inserted into the upper side of the ceiling surface 33a through the opening 33C in the same direction as the direction in which the pair of engaging portions 62, 62 face each other (in this embodiment, the width direction X2) to perform the installation work.

[0052] As shown in Figures 7 and 8, the fire extinguisher 61 is equipped with a fire detection unit 66 that detects a fire in the internal space K1 and a fire extinguisher spray port 67 that sprays a fire extinguisher. The fire extinguisher 61 is equipped with a fire extinguisher container filled with a fire extinguisher. The fire detection unit 66 employs a heat detection sensor that detects heat in the internal space K1, but may also be a sensor that detects smoke. The fire extinguisher spray port 67 has a downward-discharge type fire extinguisher nozzle that sprays the fire extinguisher in the fire extinguisher container of the fire extinguisher 61 downward when the fire detection unit 66 detects heat.

[0053] The blocking plate 63 is provided with holes 63c, 63d that expose the fire detection unit 66 and the fire extinguishing agent spray port 67 to the internal space K1 side, respectively.

[0054] Next, the procedure for attaching the fire extinguisher unit 60 to the ceiling surface 33a will be described with reference to the drawings. First, as shown in FIGS. 8 to 10, the closing plate 63 and the locking plate 65 are integrally attached to the lower surface 61a of the fire extinguisher 61 to form the fire extinguisher unit 60.

[0055] 11(a), the fire extinguisher unit 60 is inserted into the inside of the fire extinguisher cover 33B (above the ceiling surface 33a) through the opening 33C formed in the fire extinguisher cover 33B in the internal space K1 of the booth 1. At this time, the fire extinguisher unit 60 is positioned at an angle with the pair of locking portions 62 facing up and down (the insertion direction), and the rear side of the fire extinguisher unit 60 to be inserted is first inserted all the way into the upper part of the ceiling surface 33a.

[0056] 11(b), the fire extinguisher unit 60 is inserted to the back (right side of the drawing) until the front side of the insertion direction passes through the opening 33C. In this state, the front side of the fire extinguisher unit 60 is lifted from the bottom to the top of the opening 33C, and the fire extinguisher unit 60 is rotated so that its posture is approximately horizontal. At this time, the cover plate 63 is placed on one (right) support beam 36.

[0057] Thereafter, as shown in FIG. 11(c), the fire extinguisher unit 60 is moved forward (to the left side of the drawing) in the left-right direction X2. At this time, the abutment member 65B of the locking plate 65 on the rear side (right side) of the fire extinguisher unit 60 is shifted to a position where it abuts against the support beam 36 from the right side and locks. As a result, the fire extinguisher unit 60 is positioned in the left-right direction X2. Then, as shown in FIG. 4, the fire extinguisher unit 60 is lowered at the positioned position, whereby the fire extinguisher unit 60 is installed in a predetermined position on the ceiling surface 33a. At this time, the closing plate 63 closes the opening 33C. The fire extinguisher unit 60 installed on the ceiling surface 33a is fixed to the fire extinguisher 61 from below the ceiling surface 33a with bolts or the like.

[0058] In the booth 1 configured in this manner, the fire extinguisher unit 60 can be installed above the ceiling surface 33a from inside the booth 1 (the interior space side) through the opening 33C provided in the ceiling surface 33a. This has the advantage of eliminating the cumbersome task of installing a fire extinguisher from outside the booth, as was previously the case. In this case, the fire extinguisher unit 60 can be installed on the ceiling surface 33a simply by attaching it to the ceiling surface 33a, and the opening 33C can be blocked by part of the underside of the fire extinguisher unit 60 after installation, eliminating the need for the task of blocking the opening 33C after installation. In this way, in the booth 1 according to this embodiment, the fire extinguisher 61 can be efficiently installed on the ceiling surface 33a.

[0059] Furthermore, in this embodiment, the opening 33C formed in the ceiling surface 33a only needs to be large enough to allow the fire extinguisher unit 60 to be inserted from the internal space K1 side to the upper side of the ceiling surface 33a, and does not need to have the same size or shape as the fire extinguisher unit 60 in a plan view when viewed from above and below in an installed state, so the opening can be made small. In other words, the degree of freedom of the opening 33C can be increased, which reduces space restrictions caused by the opening 33C and allows other booth equipment to be installed on the ceiling surface 33a to be efficiently arranged.

[0060] Furthermore, in the booth 1 according to this embodiment, a blocking plate 63 that blocks the opening 33C can be separately engaged with the underside 60a of the fire extinguisher unit 60, so that the blocking plate 63 can be provided in a shape that fits the ceiling surface 33a around the opening 33C. Therefore, even if the underside 61a of the fire extinguisher 61 does not match the shape of the opening 33C, by engaging the blocking plate 63 with the underside 61a of the fire extinguisher 61, the opening 33C can be easily installed in a flat state along the ceiling surface 33a. In this case, by using the same material and color for the blocking plate 63 as the ceiling surface 33a, the appearance of the portion exposed in the opening 33C and the ceiling surface 33a is not impaired, and the design can be improved.

[0061] Furthermore, in the booth 1 according to this embodiment, when the blocking plate 63 is placed at the opening 33C, the fire detection unit 66 and the extinguishing agent spray port 67, which are functional parts of the fire extinguisher 61, are exposed to the interior space K1 side. Therefore, even if the blocking plate 63 is placed to block the opening 33C when the fire extinguisher 61 is installed, the function of the fire extinguisher 61 can be maintained, a fire can be reliably detected, and the extinguishing agent can be reliably sprayed on the interior space K1 side of the booth 1.

[0062] Furthermore, in the booth 1 according to this embodiment, when the fire extinguisher unit 60 is inserted from the opening 33C to the upper side of the ceiling surface 33a and the locking portion 62 is locked to the upper surface of the ceiling surface 33a, the fire extinguisher unit 60 can be easily positioned and installed by moving the fire extinguisher unit 60 in a direction along the surface of the ceiling surface 33a and causing the abutment member 65B provided on one of the locking portions 62 (locking plate 65) to abut against the support beam 36 of the ceiling surface 33a.

[0063] Furthermore, in the booth 1 according to this embodiment, a portion of the lower part of the fire extinguisher unit 60 is housed in a downward recess that is lower than the ceiling surface 33a, thereby reducing the height of the fire extinguisher unit 60 that is above the ceiling surface 33a. This reduces the distance between the ceiling surface 33a and the ceiling wall 33 (upper wall) of the booth 1, thereby reducing the height of the booth 1 itself. In this embodiment, the downward recess in the ceiling surface 33a functions as a housing for the fire extinguisher unit 60 and also functions as a cover that covers the fire extinguisher unit 60. Furthermore, in this embodiment, when attaching the fire extinguisher unit 60 to the ceiling surface 33a, the fire extinguisher unit 60 is attached to the opening 33C of the fire extinguisher cover 33B, which is located below the ceiling surface 33a, so that the work can be performed at a lower position, improving workability.

[0064] Furthermore, in the booth 1 according to this embodiment, the height of the fire extinguisher 61 can be accommodated by both the internal space K1 of the booth 1 and the space from the ceiling surface 33a to the upper surface of the ceiling wall 33 of the booth 1. Therefore, the amount of projection of the fire extinguisher cover 33B into the internal space K1 of the booth 1 can be reduced while keeping the height of the booth 1 itself low.

[0065] Furthermore, in the booth 1 according to this embodiment, even if a fire extinguisher cover 33B that is recessed below the ceiling surface 33a is provided, lighting 74 is provided on the underside 33d of the fire extinguisher cover 33B, so that the light emitted from lighting 74 is not blocked by the fire extinguisher cover 33B, making it possible to provide a booth that is easy to use.

[0066] (Variation) Next, the configuration of a booth 1A according to a modification of the above-described embodiment will be specifically described with reference to FIG. As shown in Fig. 12, the booth 1A of the modified example has a configuration different from that of the embodiment shown in Fig. 7 etc., in terms of the shape of the fire extinguisher 61 of the fire extinguisher unit 60 and the shape of the fire extinguisher cover 33B provided on the ceiling surface 33a. In the following explanation of the modified example, the fire extinguisher unit 80 and the lower cover 34, which have different configurations from those of the above embodiment, will be mainly described.

[0067] The lower cover 34 (blocking plate) according to the modified example blocks the opening 33E in the ceiling surface 33a and covers the fire extinguisher 81 provided on the ceiling surface 33a from below. The fire extinguisher 81 according to the modified example is disposed above the lower cover 34. The opening 33E in the ceiling surface 33a is large enough to allow the fire extinguisher 81 of the fire extinguisher unit 80 to pass through. Here, while in the above-described embodiment, the opening 33C is provided in the fire extinguisher cover 33B as shown in FIG. 5, the modified example differs in that the opening 33E is formed in the ceiling surface 33a. In other words, the lower cover 34 of the modified example does not have an opening through which the fire extinguisher 81 can pass.

[0068] The lower cover 34 has a central portion 34A, inclined side portions 34B, and an outer peripheral edge portion 34C. The outer peripheral edge portion 34C has a flange shape that can be bolted from below to the peripheral lower surface 33e of the opening 33E. The central portion 34A is located below the outer peripheral edge portion 34C (ceiling surface 33a) when the lower cover 34 is attached to the ceiling surface 33a. The inclined side portions 34B are inclined downward from the outer peripheral edge portion 34C toward the central portion 34A. The central portion 34A is formed with a pair of holes 34a, 34b for exposing a fire detection portion 86 and a fire extinguishing agent spray port 87 provided on the fire extinguisher 81.

[0069] The fire extinguisher unit 80 includes a fire extinguisher 81 that contains a fire extinguisher agent, and an upper cover 82 that supports the fire extinguisher 81 from above and is fixed to the peripheral upper surface 33f of the opening 33E. A first fixing jig 83 is provided on the upper part of the fire extinguisher 81 to fix it to the upper cover 82. A fire detection unit 86 that detects a fire in the internal space K1, and a fire extinguisher spray port 87 that sprays a fire extinguisher are provided on the lower part of the fire extinguisher 81.

[0070] The upper cover 82 is formed in a cylindrical shape with a top and has a locking flange 82a (locking portion) on its lower edge. The locking flange 82a is fixed to the peripheral upper surface 33f of the opening 33E and is fixed to the upwardly protruding convex portion 33F with screws 82b. A second fixing jig 84 for fixing the upper cover 82 to the first fixing jig 83 of the fire extinguisher 81 is provided in the center of the lower surface of the upper cover 82.

[0071] The first fixing jig 83 is provided with an upwardly protruding, horizontally elongated engagement portion 831. The second fixing jig 84 is formed with an elongated hole (not shown) into which the engagement portion 831 of the first fixing jig 83 can be inserted. By inserting the engagement portion 831 into the elongated hole and rotating it, the engagement portion 831 is prevented from slipping out downward from the elongated hole.

[0072] The fire extinguisher 81 is housed between the upper cover 82 and the lower cover 34, is fixed in a suspended state to the upper cover 82 fixed to the ceiling surface 33a, and is covered from below by the lower cover 34.

[0073] When attaching the fire extinguisher 81 to the ceiling surface 33a of the booth 1A, first, the lower cover 34 is removed from the ceiling surface 33a to expose the opening 33E. The upper cover 82 is previously fixed to the convex portion 33F of the ceiling surface 33a. Next, the fire extinguisher 81 alone is inserted into the inside of the upper cover 82 from below through the opening 33E, and the first fixing jig 83 of the fire extinguisher 81 is fixed to the second fixing jig 84 of the upper cover 82. Specifically, the engaging portion 831 of the first fixing jig 83 is inserted into the elongated hole of the second fixing jig 84, and the engaging portion 831 is rotated, for example, 90° together with the fire extinguisher 81, thereby engaging the upper and lower fixing jigs 83, 84 with each other. As a result, the fire extinguisher 81 is fixed to the upper cover 82, and can be installed at a predetermined position on the ceiling surface 33a from the interior space K1 side of the booth 1A. To remove the fire extinguisher 81 from the upper cover 82, simply follow the installation procedure in reverse.

[0074] The upper cover 82 may be fixed to the ceiling surface 33a in advance, or may be installed at the same time as the fire extinguisher 81 is installed on the ceiling surface 33a.

[0075] In the booth 1A according to the modified example, the fire extinguisher 81 can be installed above the ceiling surface 33a from inside the booth 1A (the internal space K1 side) through an opening 33E provided in the ceiling surface 33a. This has the advantage of eliminating the cumbersome task of installing a fire extinguisher from outside the booth as in the conventional case. In this case, after the fire extinguisher unit 80 is installed on the ceiling surface 33a, a portion of the underside of the fire extinguisher unit 80 (here, the upper cover 82) can block the opening 33E, allowing the fire extinguisher 81 to be installed on the ceiling surface 33a efficiently.

[0076] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the embodiment described above, the fire extinguisher unit 60 has the blocking plate 63 that is provided separately from the fire extinguisher 61 and is engaged with at least a part of the underside 61a of the fire extinguisher 61, and that is formed to the same size as the opening 33C, but it is also possible to omit the blocking plate 63. In this case, the opening 33C is blocked by the underside 61a of the fire extinguisher 61, and the underside 61a of the fire extinguisher 61 is exposed to the ceiling surface 33a.

[0077] In this embodiment, one of the pair of locking portions 62 is provided with a locking plate 65 provided with an abutment member 65B that positions the fire extinguisher 61 in the surface direction of the ceiling surface 33a, but it is also possible to omit such abutment member 65B and locking plate 65. Also, the abutment member may be provided integrally with the lower surface 61a of the fire extinguisher 61.

[0078] In addition, in this embodiment, the ceiling surface 33a is shaped to have a fire extinguisher cover 33B with a downwardly recessed recess, but the ceiling surface 33a may be flat overall and not have such a fire extinguisher cover 33B formed thereon.

[0079] Furthermore, the dimensions of the fire extinguisher 61, the blocking plate 63, and the fire extinguisher cover 33B can be set arbitrarily. The key is that the fire extinguisher unit 60 should be able to pass through the opening 33C.

[0080] For example, although the shape of the blocking plate used in the blocking plate 63 of the above-described embodiment is rectangular in plan view, it is not limited to a rectangular shape. In short, as long as the blocking plate has two opposing parallel sides (parallel sides 63a) and is further provided with a connecting side 63b connecting the ends of the opposing parallel sides 63a, and the fire extinguisher unit does not protrude outward from this connecting side 63b, it can be inserted from the interior space through the opening to the upper side of the ceiling surface. The shape of the blocking plate may be, for example, blocking plates 63A, 63B, 63C, and 63D according to modifications shown in FIGS. 13(a) to 13(d). These plates have a pair of parallel sides 63a and a pair of connecting sides 63b. The blocking plate 63A shown in FIG. 13(a) is trapezoidal in plan view. The blocking plate 63B shown in FIG. 13(b) is hexagonal in plan view. The blocking plate 63C shown in FIG. 13(c) has one connecting side 63b that is a straight line perpendicular to the parallel sides 63a, and the other connecting side 63b is a convex curve that protrudes outward. The blocking plate 63D shown in FIG. 13(d) has both connecting sides 63b that are irregularly curved. In all of these blocking plates 63A to 63D according to modifications, the positions of the fire detection unit 66 and the fire extinguishing agent spray port 67 can be set arbitrarily.

[0081] In addition, in this embodiment, the sliding door supported by the guide rail 51 is of a swing type, but it is not limited to a swing type. In short, it is sufficient that the guide rail provided on the ceiling surface 33a is arranged on one side of the ceiling surface in the width direction perpendicular to the front-to-rear direction of the booth, and for example, the guide mechanism can be applied to a sliding door that can be opened and closed linearly in the width direction.

[0082] In the embodiment, the booth 1 has been described as one in which only one user can enter the internal space K1. However, the present invention is not limited to this and can also be applied to a booth in which multiple people can enter the internal space K1.

[0083] In addition, the underside of the fire extinguisher cover may extend toward the wall where the work area is located (in this embodiment, toward the wall at the back as seen from the booth entrance), and lighting may be provided at that extended point. This brings the lighting closer to the work area, which has the effect of efficiently illuminating the work area.

[0084] In addition, within the scope of the spirit of the present invention, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described modifications may be combined as appropriate. [Explanation of symbols]
