Description

[Technical Field]

[0001] The present invention relates to a booth used for office work, meetings, etc. [Background technology]

[0002] Booths that can suppress the intrusion of external noise and human voices and increase the concentration of people in the interior space have been known for some time. In the booth industry of this type, a notice titled "Regarding the Submission of Work Documents Related to Firefighting Equipment, etc." (Fire Prevention Notice No. 622) issued by the Fire and Disaster Management Agency on November 2, 2018, made widely known a special measure that allows exemption from the previously required installation of sprinkler heads, etc., by installing a downward-discharge automatic fire extinguishing device for residential use (see, for example, Non-Patent Document 1) in a mobile booth.

[0003] For this reason, it has become common practice in recent years for this type of booth to be equipped with a downward-discharge type automatic fire extinguishing device on the ceiling (see, for example, Non-Patent Document 2).

[0004] This type of downward-discharge automatic fire extinguishing system generally has an extinguishant spray nozzle and other components integrally mounted on the underside of a fire extinguishant storage container, and the fire extinguishant storage container is housed in a cover, for example, which is then attached to the exterior surface of the booth ceiling together with the fire extinguishant storage container and the fire extinguishant spray nozzle, etc. In other words, with conventional systems, it is necessary to attach the fire extinguishing system to the top surface of the ceiling board from the exterior space side.

[0005] Recently, this type of booth has increasingly been deemed a "habitable room" under the Building Standards Act, which often requires the interior space to be at least 2100 mm high. However, this type of booth is sometimes installed in office spaces with ceiling heights of, for example, around 2300 mm, which leaves only a narrow space between the booth ceiling and the external architectural ceiling. In such an environment, installing a fire extinguishing system from above on the booth ceiling requires a cramped operation.

[0006] This problem can also occur when the fire extinguishing device is not provided with a cover and is installed in an exposed state on the ceiling panel of the booth, and some kind of countermeasure is desired. [Prior art documents] [Non-patent literature]

DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0016] In this embodiment, the present invention is applied to a booth B for one person.

[0017] As shown in Figures 1 and 2, this booth B comprises a base 1 that covers the underside of the internal space IS, peripheral walls (front wall 2, side wall 3, back wall 4) that surround the internal space IS, and a ceiling 5 that covers the top of the internal space IS, and a table 6 and chairs 7 are provided in the internal space IS.

[0018] 1 and 2, the base plate 1 is provided on its underside with casters 17, adjusters 18, and fixtures 19. The casters 17 are for moving the booth B along the building floor surface, the adjusters 18 are for adjusting the height of the four corners of the booth B after it has been moved, and the fixtures 19 are for fixing the booth B to the building floor surface using anchor bolts or the like (not shown) after the height of the four corners has been adjusted.

[0019] The front wall 2, which serves as a peripheral wall, closes the front of the interior space IS and, as shown in Figures 1 and 2, is equipped with a left fixed frame 21, a central door panel 22, and a right fixed frame 23. The door panel 22 is mainly made of laminated glass, for example, and is hinged to the left fixed frame 21 via a hinge 22d so that it can be opened and closed. In the figures, reference numeral 22e denotes a handle.

[0020] 1 to 3, the side wall 3 serving as a peripheral wall comprises an outer panel 31, a sound-absorbing material (not shown) attached to the inner surface of the outer panel 31, and an interior sound-absorbing panel 35 arranged inside the sound-absorbing material. An air flow path 3F is formed between the outer panel 31 and the sound-absorbing panel 35, and a notch 35a is formed in the upper edge of the uppermost sound-absorbing panel 35 to guide air in the interior space IS through the air flow path 3F to an air flow path 5F in the ceiling 5, which will be described later.

[0021] 1 and 2, the rear wall 4, which is a peripheral wall, is formed by disposing a fixing panel 42 between a left fixing frame (not shown) and a right fixing frame (not shown). The fixing panel 42 is mainly made of laminated glass, for example.

[0022] As shown in Figures 3, 4, 9, and 16, the ceiling 5 has a double-wall structure including a ceiling panel 51, which is a ceiling portion separating an internal space IS from an external space OS, and an interior ceiling panel 56 arranged below the ceiling panel 51 via an air flow path 5F. The ceiling panel 51 is made of, for example, sheet metal, and horizontal reinforcements 52 extending laterally are rigidly connected to its underside by welding or the like. The interior ceiling panel 56 is, for example, made by laminating two sound-absorbing panels 561, and an outer frame 562 is fitted to the periphery of the panels. The outer frame 562 is fastened to the ceiling panel 51 via brackets 55. An air flow path 5F is formed between the ceiling panel 51 and the interior ceiling panel 56, allowing air to circulate. The ceiling panel 51 is provided with an air vent 57 for releasing air in the air flow path 5F to the external space OS. The air flow path 5F communicates with the interior space IS through the cutouts 35a of the sound-absorbing panels 35 that abut the undersides of both left and right ends of the interior ceiling board 56. The interior ceiling board 56 is provided with downlights 59 and the like for illuminating the interior space IS.

[0023] 3, 4, 7 to 9, 11, 16, and 17, a downward-discharge type fire extinguisher 8 having an extinguishant storage container 81 and an extinguishant spray nozzle 82 integrally mounted thereon is disposed on the ceiling 5. That is, the booth B is provided with a ceiling board 51 that separates the interior space IS from the exterior space OS, and the ceiling board 51 supports the fire extinguisher 8 having the extinguishant storage container 81 and the extinguishant spray nozzle 82. The booth B is also provided with a container holder 53 that holds the extinguishant storage container 81, and mounting means 54 for mounting the container holder 53 together with the extinguishant storage container 81 to the ceiling board 51 from the interior space IS side. When the container holder 53 is attached to the ceiling board 51, at least a portion of the extinguishant storage container 81 protrudes toward the external space OS through a square skylight 51a formed in the ceiling board 51 in a plan view, and the extinguishant spray nozzle 82 is configured to face the internal space IS.

[0024] As shown in FIGS. 3, 4, 7-9, 11, 16, and 17, the fire extinguisher 8 integrally comprises a fire extinguishant storage container 81 and a fire extinguishant spray nozzle 82 having a sensor protruding from the center of the lower end of the fire extinguishant storage container 81. The fire extinguisher 8 of this embodiment is a typical downward-discharge automatic residential fire extinguishing device (SPA-5 Sprinkler Ace manufactured by Nippon Dry Chemical Co., Ltd.) that has been sold for many years and is well known, so detailed explanations of its structure and operation will be omitted. In the drawings, reference numeral 83 denotes an indicating pressure gauge protruding from the lower surface of the fire extinguishant storage container 81, and 84 denotes a pressure filling port. The fire extinguishant storage container 81 has a shape whose planar cross section gradually decreases downward from the vertical middle position. Specifically, because the planar cross sections of each part of the fire extinguishant storage container 81 of this embodiment are circular, the lower half of the fire extinguishant storage container 81 has a circular planar cross section whose diameter gradually decreases downward. This fire extinguisher 8, while held by the container holder 53, can be attached to the portion of the ceiling board 51 where the skylight 51a is formed, from the interior space side IS.

[0025] 3, 4, 7 to 9, 11, 16, and 17, container holder 53 is a flat plate-like structure that is rectangular in plan view and has a circular opening 53x in the center, into which the lower half of extinguishant storage container 81 fits from above. Opening 53x has a diameter smaller than the diameter (maximum diameter) of the equator of fire extinguishant storage container 81, and by placing the lower half of fire extinguishant storage container 81 on opening 53x from above, fire extinguishant storage container 81 is stably held in container holder 53. Container holder 53 can be attached to ceiling board 51 together with fire extinguishant storage container 81 from the internal space IS side by attachment means 54. 10 to 15, this mounting means 54 is configured, for example, by providing a skylight 51a in the center of ceiling plate 51 and having a rectangular shape in plan view with four sides (left side 51a1, right side 51a2, front side 51a3, and rear side 51a4), with a plurality of downward nuts 541 fixed to the outside of the edge of skylight 51a, and bolt insertion holes 53a, 53b are formed in the vicinity of the periphery of container holder 53 corresponding to each downward nut 541. Then, container holder 53 holding a fire extinguishant storage container 81 is attached to the underside of ceiling plate 51 while holding fire extinguishant storage container 81 so that the fire extinguishant storage container 81 passes through skylight 51a, and bolts v1 inserted into each bolt insertion hole 53a, 53b from the internal space IS side are screwed into the corresponding downward nuts 541, thereby fastening container holder 53 to ceiling plate 51.

[0026] 7, 8, and 11, the container holder 53 of this embodiment has a bolt insertion hole 53b formed on its right edge that is a notch that opens outward. Therefore, bolts v1 are loosely and temporarily screwed into downward nuts 541 arranged along the right side 51a2 of the skylight 51a of the ceiling plate 51, and the bolts v1 are temporarily engaged in the bolt insertion holes 53b at the right end of the container holder 53, thereby facilitating the process of screwing the container holder 53 to the ceiling plate 51.

[0027] In this embodiment, as shown in Figures 1 to 4, a cover 50 is provided to prevent the extinguishant storage container 81 supported by the container holder 53 from being exposed to the external space OS. As shown in Figures 5, 6, 9, and 11 to 15, the cover 50 is fastened to the ceiling panel 51 from the internal space IS side, and is configured so that when attached to the ceiling panel 51, a portion of the cover 50 protrudes toward the external space OS through a skylight 51a. More specifically, as shown in Figures 5, 9, and 12 to 15, the cover 50 is mainly composed of a box-shaped cover main body 501 including surrounding plates (left and right side plates 502, 503, a front plate 504, and a rear plate 505) that surround the extinguishant storage container 81 and an upper plate 506 that closes the upper ends of the surrounding plates 502 to 505, and an outwardly extending flange 507 is provided at the edge of the opening at the lower end of the cover main body 501. Cover body 501 has a rectangular shape in plan view and is box-shaped so that it can be inserted from below into rectangular skylight 51a formed in ceiling panel 51. Flange 507 has approximately the same outer edge shape as container holder 53 described above in plan view, and is provided with bolt insertion holes 508a, 508b of the same shape at locations corresponding to bolt insertion holes 53a, 53b drilled in container holder 53. That is, when cover 50 is placed over container holder 53 holding fire extinguishant storage container 81, cover body 501 covers fire extinguishant storage container 81, and flange 507 abuts against the upper surface of container holder 53 near its periphery, so that bolt insertion holes 508a, 508b in flange 507 align with bolt insertion holes 53a, 53b in container holder 53. In this state, the container holder 53 can be lifted together with the fire extinguishant storage container 81 and the cover 50 and attached to the ceiling plate 51 from the side of the internal space IS as described above. When the temporarily fastened bolt v1 is engaged with the notched bolt insertion holes 53b, 508b formed in the right end of the container holder 53 and the right end of the flange 507 of the cover 50, the cover 50 must be slightly tilted or moved horizontally together with the container holder 53, and therefore the left-right dimension of the cover main body 501 is set smaller than the left-right dimension of the skylight 51a.

[0028] Furthermore, in this embodiment, the cover 50 described above can also be fastened to the ceiling board 51 from the exterior space OS side (in this specification, the mode in which the cover 50 is attached from the exterior space OS side is sometimes referred to as the "sub-attachment mode," and the mode in which the cover 50 is attached from the interior space IS side is sometimes referred to as the "main attachment mode"). More specifically, each of the downward nuts 541 described above is fastened to the ceiling board 51 by welding or the like with its large-diameter head 541a protruding from the upper surface of the ceiling board 51, but as shown in FIGS. 16 to 21, the cover 50 is configured so that it can be placed on the upper surface of the ceiling board 51 in a state in which it is horizontally rotated 90 degrees around the center of the skylight 51a. That is, an interference prevention hole 509 is formed in the flange 507 of the cover 50, into which the head 541a of each downward nut 541 can enter when it is horizontally rotated 90 degrees. Further, upward nuts 511 are fixed to the portions of the ceiling plate 51 corresponding to the bolt insertion holes 508a, 508b formed in the flange 507 of the cover that has been horizontally rotated 90 degrees. Therefore, after placing the cover 50 that has been horizontally rotated 90 degrees on the upper surface of the ceiling plate 51, the bolts v2 inserted from above into the bolt insertion holes 508a, 508b of the flange 507 are screwed into the corresponding upward nuts 511 of the ceiling plate 51 from above, thereby attaching the cover 50 to the ceiling plate 51 from the external space OS side. Note that the upward nuts 511 are fastened to the ceiling plate 51 with their large-diameter heads 511a protruding from the underside of the ceiling plate 51 but not from the upper side of the ceiling plate 51. The upward nuts 511 are provided at a position on the underside of the ceiling plate 51 so that their heads 511a do not interfere with the container holder 53.

[0029] 1, 3 to 6, 9, 11, and 15, the booth B of this embodiment is equipped with a container holder 9 for preventing the fire extinguishant storage container 81 from coming off the container holder 53. More specifically, as shown in FIGS. 3 to 5, 9, 11, and 15, the container holder 9 includes a base plate 91 having a pair of bolt insertion holes 91a and a single interference prevention hole 91b, an upright plate 92 standing vertically from the inner end of the base plate 91, and an extension plate 93 extending inward from the upper end of the upright plate 92. A bolt insertion hole 51x corresponding to the bolt insertion hole 91a of the base plate 91 is formed near the left edge of the ceiling plate 51, and an upward nut 531 is fixed to the corresponding portion of the container holder 53. Furthermore, a side window 502a is formed in the left side panel 502, which is a peripheral panel of the cover body 501, for inserting the extension plate 93 of the container holder 9 into the cover body 501. By screwing the base plate 91 of the container holder 9 into the upward-facing nut 531 of the container holder 53 using the bolt v3, the extension end 93a of the extension plate 93 of the container holder 9 abuts against a portion of the fire extinguishant storage container 81 that is higher than the equator. Note that this description is for the main installation mode in which the cover 50 is installed from the internal space IS side. In the sub-installation mode in which the cover 50 is installed from the external space OS side, the container holder 9 is installed behind the skylight 51a of the ceiling panel 51, as shown in Figures 16, 17, and 20. Therefore, a pair of upward-facing nuts 511 for the container holder are fixed behind the skylight 51a of the ceiling panel 51.

[0030] As shown in Figures 3, 4, 9 and 16, an interior ceiling plate 56 is arranged on the underside of the ceiling plate 51 that supports the fire extinguisher 8, covering the extinguishant storage container 81 and the container holder 53 from below, and this interior ceiling plate 56 has an opening 56a formed therein to allow the nozzle 82 to face the internal space IS.

[0031] 1 to 15 show a main installation mode in which the cover 50 is installed together with the container holder 53 from the interior space IS side, and the assembly procedure can be summarized as follows. First, before installing the sound-absorbing panels 35 on the side walls 3 and the interior ceiling board 56 on the ceiling 5, the container holder 53 holding the extinguishant storage container 81 of the fire extinguisher 8 is installed on the ceiling board 51 from the interior space IS side. That is, the lower half of the extinguishant storage container 81 is fitted from above into the opening 53x of the container holder 53, thereby holding the extinguishant storage container 81 in the container holder 53. When the cover 50 is placed on the container holder 53 in this state, the extinguishant storage container 81 is fitted into the cover main body 501, and the flange 507 of the cover 50 is attached to the upper peripheral surface of the container holder 53, thereby forming the fire extinguisher unit U. By lifting this fire extinguisher unit U upward from the internal space IS side and projecting the cover body 501 toward the external space OS through the skylight 51a of the ceiling board 51, the upper surface of the peripheral edge of the container holder 53 can be brought into abutment with the underside of the ceiling board 51 via the flange 507 of the cover 50. In this state, as shown in Figures 4, 7, and 13 to 15, the fire extinguisher unit U can be attached to the ceiling board 51 by passing bolts v1 from the internal space IS side through bolt insertion holes 508a, 508b provided in the container holder 53 and the flange 507 of the cover 50 and screwing them into downward nuts 541 of the ceiling board 51. When installing the fire extinguisher by one person, it is possible to loosen bolts v1 only on the downward bolts 541 near the right side 51a2 of the skylight 51a, and engage these bolts v1 with notched bolt insertion holes 53b, 508b formed in the right edge of the flange 507 of the container holder 53 and the cover 50. In this way, it is not necessary to support the entire fire extinguisher unit U from below during the initial bolt fixing work, and one person can easily complete the screw tightening work.

[0032] After the fire extinguisher unit U is attached to the ceiling plate 51 from the internal space IS side in this way, an interior ceiling plate 56 is placed below the ceiling plate 51 and fastened to the inside edge of the ceiling plate 51 via brackets 55. In this state, the cover body 501 and most of the fire extinguishant storage container 81 protrude toward the external space OS through the skylight 51a formed in the ceiling plate 51, and the fire extinguishant spray nozzle 82 and indicated pressure gauge 83 integrally provided at the lower end of the fire extinguishant storage container 81 face the internal space IS through the opening 56a formed in the interior ceiling plate 56.

[0033] In this embodiment, the container holder 9 alone can be retrofitted from the exterior space OS side. That is, when the fire extinguisher unit U, which includes the container holder 53 holding the fire extinguishant storage container 81, is attached to the ceiling board 51 by the above-described procedure, and an operator moves toward the exterior space OS, the operator can see from the side of the booth B the side window 502a formed in the side board 502 of the cover 50 and the bolt insertion hole 508a corresponding to the upward nut 531 for attaching the container holder. Therefore, by inserting the extension plate 93 of the container holder 9 into the side window 502a and abutting against the fire extinguishant storage container 81, and screwing the base plate 91 of the container holder 9 to the container holder 53 with the bolt v3 as shown in FIGS. 4, 5, and 15, the fire extinguishant storage container 8 can be held on the container holder 53 without misalignment or the like. The aforementioned bolt v3 is threaded into the upward nut 531 of the container holder 53 through the bolt insertion hole 51x of the base plate 91 and the ceiling plate 51, and it is preferable to use a hand-tightenable type such as a knurled screw or a urea screw.

Note that the interior ceiling panel 56 is omitted in FIGS. 7 and 8. FIG. 10 is an enlarged plan view of the ceiling panel 51 of this embodiment. FIG. 11 is an enlarged plan view of the ceiling 5 of this embodiment. Note that FIGS. 10 and 11 each show an enlarged view of the area corresponding to area X in FIG. 6. 10 omits the cover 50 and the container holder 53.

FIG. 14 is an enlarged view of a cross section taken along line cc in FIG. 11 . FIG. 15 is an enlarged view of a cross section taken along line dd in FIG. 11 . As mentioned above, FIGS. 1 to 15 show a main mounting mode in which the cover 50 is mounted together with the container holder 53 from the internal space IS side. Meanwhile, as also mentioned above, FIGS. 16 to 21 show a sub-mounting mode in which the cover 50 is mounted from the external space OS side. FIG. 16 is an exploded perspective view of the ceiling 5. FIG. 17 is an enlarged plan view of the ceiling 5. FIG. 17 shows an enlarged view of the region corresponding to region X in FIG. 6 .

FIG. 20 is an enlarged view of a cross section taken along line gg in FIG. 17 . FIG. 21 is an enlarged view of a cross section taken along line hh in FIG.

[0035] With this configuration, the fire extinguishant storage container 81 and the container holder 53 that holds this fire extinguishant storage container 81 can be attached to the ceiling panel 51 from the side of the internal space IS. Therefore, even if the architectural ceiling of the external space OS is relatively low and only a narrow space remains between it and the ceiling 5 of the booth B, it is possible to easily attach the fire extinguisher 8 having the relatively bulky fire extinguishant storage container 81 to the ceiling 5 of the booth B. In other words, with this configuration, even if the ceiling 5 of the booth B is set high to provide ample space in the internal space IS, it is possible to place the fire extinguisher under a relatively low architectural ceiling without making the installation work difficult, and it is possible to reasonably increase the degree of freedom in placement while complying with the Building Standards Act and the like.

[0036] Furthermore, in this embodiment, the cover 50 that covers almost the entire extinguishant storage container 81 is provided, so that the fire extinguisher 8 can be prevented from being exposed to the outside space OS.

[0037] Moreover, in this embodiment, the cover 50 can be attached to the ceiling panel 51 not only from the interior space IS side but also from the exterior space OS side, allowing the optimal assembly procedure to be selected depending on various external environments. FIGS. 16 to 21 show a sub-mounting mode in which the cover 50 is attached to the ceiling panel 51 from the exterior space OS side. In the sub-mounting mode, the container holder 53 and the fire extinguishing agent storage container 81 are first attached to the ceiling panel 51 using a procedure similar to that of the main mounting mode, and then the cover 50 is attached from the exterior space OS side. At this time, the cover 50 assumes a position that is horizontally rotated 90 degrees from the position in the main mounting mode. Then, in this horizontally rotated position, the cover 50 is placed on the ceiling panel 51 and fastened with screws. 18, bolt v2 used in this case is threaded through bolt insertion holes 508a, 508b formed in flange 507 and into upward nuts 511 fixed to ceiling plate 51, and these upward nuts 511 can be positioned so as not to interfere with container holder 53 because cover 50 is attached by rotating it horizontally by 90 degrees. Note that this sub-attachment mode is adopted when there is a relatively ample external space OS above ceiling plate 51, and therefore, as shown in FIG. 22, only container holder 53 may be attached to ceiling plate 51 from the internal space IS side, and fire extinguishant storage container 81 and cover 50 may be attached from the external space OS side.

[0038] Furthermore, in this embodiment, since a retrofitted container holder 9 is provided, the initial holding mode of the fire extinguishant storage container 81 relative to the container holder 53 can be a configuration in which the fire extinguishant storage container 81 is simply placed on the opening of the container holder 53, thereby simplifying the container holding structure.

[0039] It goes without saying that the present invention is not limited to the above description, and various modifications are possible without departing from the spirit of the present invention.

[0040] For example, the booth is not limited to one for one person, but may be one for two or more people.

[0041] The present invention also includes embodiments that do not have a cover. Even when a cover is provided, the cover may be one that can only be attached to the ceiling portion (ceiling board) from the interior space side, or one that can only be attached from the exterior space side, etc.

[0042] Furthermore, the present invention also includes embodiments that do not include a container holder. Even when a container holder is included, the container holder is not limited to being an after-market attachment. For example, immediately after the fire extinguishant storage container is attached to the container holder, the container holder may be screwed to the container holder to stably hold the fire extinguishant storage container, and then a cover may be attached to the container holder. In this case, it is desirable to position the container holder in a position that does not interfere with the cover, such as a position corresponding to a recessed corner of the cover body. Various modifications are possible regarding the means for stably holding the fire extinguishant storage container on the container holder. Furthermore, even when a special container holder is used, its attachment location is not limited to the container holder, and it may be provided, for example, on the ceiling (ceiling panel).

[0043] In addition, although the illustrated embodiment describes a case where an interior ceiling panel is disposed below the ceiling portion (ceiling panel), the interior ceiling panel is not necessarily required for the present invention. However, providing such an interior ceiling panel not only improves the appearance of the interior space, but also improves the sound absorption performance within the room, and further provides effects such as forming an air flow path between the interior ceiling panel and the ceiling panel, allowing air within the interior space to be smoothly exhausted to the exterior space.

[0044] The type of the ceiling is not limited to the ceiling board as in the illustrated embodiment, but may be of various shapes and materials.

[0045] In addition, various modifications may be made without departing from the spirit of the present invention. [Explanation of symbols]
